  2. 47. Search for SM Higgs at the Tevatron (high mass)
    Dr Lidija Zivkovic (Columbia University)
    02/03/2008 09:00
    We present here searches for the Standard Model Higgs boson at high mass. We show results of the searches in two channels, H->WW->lnulnu and WH->WWW(*)->lnulnu+X. The data were collected with the CDF and D0 detectors at the Tevatron collider at Fermilab, and correspond to an integrated luminosity of 1.1-2.4 fb^-1. In the absence of signal we set limits on the cross section in units of...

  3. 46. Electroweak symmetry breaking induced by dark matter
    Dr Michel Tytgat (ULB - Université Libre de Bruxelles)
    02/03/2008 09:20
    We will discuss a simple extension of the SM with a dark matter candidate in the form of one of the neutral components of an extra scalar doublet, the so-called Inert Doublet Model. In particular I show how the EW symmetry may be broken by loops effects from the inert doublet.

  7. 17. Electroweak constraints on see-saw messengers and their implications for LHC
    Prof. Francisco del Aguila (Universidad de Granada)
    02/03/2008 11:00
    We update the constraints from electroweak precision data on new leptons and scalars that can give Majorana masses to light neutrinos. The allowed mixings and couplings are large enough to make these particles observable at LHC, as long as an extra symmetry suppresses their contributions to light neutrino masses.

    With a few months before the LHC start-up, the commissioning of ATLAS is at its last stage while the last components of the detector are installed. The knowledge acquired during the preparation phase is presented as well as the expected performances at start-up. The strategies of both ATLAS and CMS regarding the use of early data involving leptons is then described. Assuming an integrated...

    Dr Tim Christiansen (CERN)
    02/03/2008 19:05
    With the first collisions from the LHC in sight, the CMS experiment has entered the final stage of commissioning. Nearly all of the detectors have been installed in the experiment and the last heavy structure of CMS was lowered into the experimental hall in January 2008. The CMS collaboration has launched a series of combined data-taking exercises, so-called Global Runs, with increasing scope...

On these 2 latest topics combined H1-ZEUS...

  18. 1. Gravitino Dark Matter and Collider Implications
    Dr Frank Steffen (MPI of Physics)
    03/03/2008 08:50
    Considering gravitino dark matter scenarios, cosmological constraints on the sparticle masses and on the reheating temperature of inflation will be discussed. These constraints are relevant for prospects of phenomenology at the LHC and for our understanding of inflation and the baryon asymmetry of the Universe.

  19. 43. The first few fb-1; Potential for observing SUSY, Higgs (SM and BSM)
    Dr Soshi Tsuno (High Energy Accelerator Research Organization, KEK)
    03/03/2008 09:10
    We outline the expected sensitivity of the discovery for SUSY and Higgs on the first few fb-1 operation of LHC. We also briefly introduce the global strategy for finding the SUSY particles, and proposed background estimation methods by data-driven analysis. This report contains both results from ATLAS and CMS experiments. With a few fb-1 data, both experiments will find SUSY particles...

  22. 15. Searches for new physics in Lepton final states
    M. Sourabh Dube (Rutgers University)
    03/03/2008 10:50
    It is hoped that new physics beyond the standard model, such as supersymmetry, will solve some of the problems with the standard model. In this talk I will describe searches for various new physics models at the Tevatron in lepton final states. Signatures with leptons in final state tend to be cleaner and with low backgrounds from standard model. The searches I describe, for example a...

  23. 33. Moduli, anomalous U(1) and LHC Phenomenology
    Dr Alberto Romagnoni (LPT - Orsay and CPHT - Polytechnique)
    03/03/2008 11:15
    In the general framework of phenomenological KKLT-like models in supergravity setup, I will talk about the case where the uplift to a Minkowski vacuum is provided by a Fayet-Iliopoulos sector in the presence of an extra anomalous U(1) symmetry. The modulus contribution to supersymmetry breaking is larger than in the models already present in the literature and a new mixed gauge-gravity...

  25. 9. Kaluza-Klein Parity for Randall-Sundrum
    M. Adam Falkowski (CERN)
    03/03/2008 17:20
    I discuss a class of models with extra dimensions that combines warped geometry of the Randall-Sundrum type and a discrete symmetry called the Kaluza-Klein (KK) parity. These models may address the little hierarchy problem present in the conventional Randall-Sundrum set-up. Moreover, the lightest Kaluza-Klein particle (LKP) is stable and can play the role of dark matter. Collider signals of...

  27. 45. Top mass and properties
    Dr Yen-Chu Chen (Institute of Physics, Academia Sinica, Taiwan, ROC)
    03/03/2008 18:00
    Ten years after the discovery of the Top quark the mass of it has been well measured assuming that this is really the Top quark of the Standard Model. Both CDF and D0 are collecting more data and just start to be sensitive to important properties of this particle (such as charge) to identify if this is really the Top quark of the Standard Model.

    Reinhard Schwienhorst (Michigan State University)

  29. 42. Supergravity : finite after all ?
    Prof. Kellogg Stelle (Imperial College London)
    03/03/2008 18:40
    Supergravity was once viewed as a possible solution to the ultraviolet problem of quantum gravity, but subsequent experience dampened the enthusiasm for this possibility, yielding instead to the expectation that only superstring theory can give an acceptable quantum theory. Recent advances in computation, however, raise once more the question whether the maximal N=8, D=4 supergravity might in...

    We report a study of semileptonic B decays to P-wave D** mesons. Semileptonic decay to D*_2 meson is observed for the first time. The result is obtained using the full reconstruction tagging method from a data sample that contains 657 millions BB pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+ e- collider.

    M. Gian Piero Di Giovanni (LPNHE - University "Pierre et Marie Curie"/IN2P3-CNRS)
    04/03/2008 11:15
    The precise determination of CP violation in the B meson system has been one of the goal of particle physics in the last decade. The Standard Model description of the CP violation phenomenology has been proved to be successful by accurate measurements using $B^+$ and $B^0$ decays at the B factories. So far, comparable experimental knowledge in the $B_s$ sector has been lacking, but the...

    M. Wojciech Fedorko (University of Chicago)
    04/03/2008 17:07
    We present a measurement of the top quark mass employing the template method with data samlpe collected by the CDF Run II detector corresponding to integrated luminosity of 2fb^-1. Lepton+Jets and Dilepton final states are selected. For each event in the Lepton+Jets channel we apply kinematic constraints on the pair of top quarks and their decay products to determine a reconstructed top quark...

  43. 41. BiPo prototype measurements for SuperNEMO
    M. Mathieu Bongrand (LAL - Universite Paris-Sud 11)
    04/03/2008 17:12
    The SuperNEMO project requires high radiopurity levels of the 2beta source foils: 10 uBq/kg in 214Bi and 2 uBq/kg in 208Tl. Today, best detectors can't reach these levels for big masses in a reasonable time. That's why the collaboration decided to build a dedicated detector for these measurements. Looking for BiPo processes (beta decay + delayed alpha decay) the BiPo detector has to measure...

  44. 35. Search for the Higgs boson in the ZH->nunubb channel at D0
    M. Christophe Ochando (LAL)
    04/03/2008 17:21
    A search for the standard model Higgs boson has been performed in 2.1 fb-1 of p_pbar collisions at 1.96 TeV, collected with the D0 detector at the Fermilab TeVatron. The final state considered is a pair of acoplanar b jets, as expected from the reaction p_pbar->HZ->bbnunu. The search is also sensitive to the HW->bblnu, when the charged lepton is not identified. Boosted decision trees were...

  47. 53. Yukawa corrections to b anti-b H production (LHC)
    M. Duc Ninh Le (LAPTH)
    04/03/2008 17:42
    We investigate the leading one-loop Yukawa corrections to the process $pp -> b\bar{b}H$ in the SM. We find that the NLO correction to the cross section is about $-4\%$ if the Higgs mass is $120$GeV. In the limit of vanishing bottom-Higgs Yukawa coupling the cross section is generated solely at the loop level. This contribution is very small at $M_H\sim 120$GeV and increases with growing...

  49. 32. Search of $K_S \to e^+ e^-$ decay with KLOE
    M. Flavio Archilli (University "Tor Vergata" (Rome))
    04/03/2008 17:56
    The KLOE detector is operated at DA$\Phi$NE, an $e^+ e^-$ collider running at a center of mass energy $W = m_{\phi} \sim 1019.45$~MeV. $\phi$ mesons decay 34\% of the time to a $K_S K_L$ pair. Detection of a $K_L$ thus signals the presence of, ``tags'', a $K_S$ and vice versa. With this technique, we select a pure $K_S$ beam, which permits studies of suppressed $K_S$ decays...

    Dr Jernej Kamenik ("Jozef Stefan" Institute and INFN LNF)

    We present an updated phenomenological analysis of MFV models, both at small and large tan beta, in the sector of Delta F=1 processes. We evaluate the bounds on the scale of new physics derived from recent measurements (in particular from B to Xs gamma, B to Xs ll and B to mu mu) and we use such bounds to derive a series of model-independent predictions for future experimental searches in...

    We discuss recent results on charm and tau physics obtained by the Belle and BaBar collaborations. In the charm section we present measurements of D0-D0bar mixing parameters, measurements searching for CP violation in D0 decays and a measurement of D_s meson decay constant. In the tau section the recent results on Lepton Flavor Violation in tau decays to three leptons or a lepton and a vector...

    Prof. Paul Harrison (University of Warwick)
    04/03/2008 19:25
    We review the recently proposed flavour-permutation-symmetric mixing observables and discuss their application to quark and lepton mixing matrices, with particular reference to tri-bimaximal mixing and its viable generalisations. We present an alternative formulation of the same idea which admits a new geometrical representation of mixing.

    We study different LFV processes, namely, $l_j \to l_i \gamma$, $l_j \to 3 l_i$ decays, $\mu-e$ conversion in nuclei and LFV semileptonic decays, within the context of the Constrained Minimal Supersymmetric Standard Model, enlarged by three right handed neutrinos and their supersymmetric partners, and where the neutrino masses are generated via a seesaw mechanism. Two different scenarios with...

    Prof. German Valencia (Iowa State University)
    05/03/2008 10:55
    The HyperCP collaboration observed three events for the decay Sigma^+ -> p mu^+ mu^-. They suggested that new physics may be required to understand the implied decay rate and the observed M_{mumu} distribution. Motivated by this result, we re-examine this mode. First within the standard model, and then assuming there is a new particle. Within the SM we find that Sigma^+ -> p mu^+ mu^- is...

    KTeV has new results on several rare and forbidden decays of the K_L and pi^0. These include newly published searches for lepton flavor violation as well as measurements of all neutral pion decays with electrons in the final state. Some of these decay modes are being measured for the first time in decades, including the pi^0 -> +e-e+e- decay which provides the only direct measurement of the...

    M. Steve Blanchet (Max-Planck-Institut fuer Physik, Munich)
    05/03/2008 17:05
    As it was recently realized, flavor effects in leptogenesis modify the established "unflavored" picture in many ways. One of them is the appearance of a link between low-energy CP violating phases and the matter-antimatter asymmetry of the Universe. In particular, the only phase in the PMNS mixing matrix that one can hope to measure in the future, i.e. the Dirac phase, can be the unique source...

    We present a measurement of the $B^0_s$ meson lifetime using fully and partially reconstructed hadronic decays $B^0_s\rightarrow D_s^- \pi^+(X)$ followed by $D_s^- \rightarrow \phi\pi^-$. The data sample was recorded with the CDF II detector at the Fermilab Tevatron and corresponds to an integrated luminosity of 1.3 fb$^{-1}$ from $p\bar{p}$ collisions at $\sqrt{s} = 1.96$ TeV.

    Unification of GUT-scale t-b-τ Yukawa couplings is a significant feature of simple SO(10) SUSY GUTs. We present the results of a search that used the Markov Chain Monte Carlo (MCMC) technique to investigate the special parameter space regions having both Yukawa unification and WMAPcompatible dark matter relic density. The regions having better than 10% Yukawa unification are characterized by a...

    Mme Chiara Arina (University of Torino and INFN)

    A thorough analysis of sneutrinos as dark matter candidates is perfomed, in different classes of supersymmetric models, as is typically done for the neutralino dark matter. First in the Minimal Supersymmetric Standard Model, sneutrinos are marginally compatible with existing experimental bounds, including direct detection, provided they compose a subdominant component of dark matter. Then...

    Dr Emiliano Molinaro (S.I.S.S.A.)

    The effects of the lightest neutrino mass in ``flavoured'' leptogenesis are investigated in the case when the CP-violation necessary for the generation of the baryon asymmetry of the Universe is due exclusively to the Dirac and/or Majorana phases in the neutrino mixing matrix U. The type I see-saw scenario with three heavy right-handed Majorana neutrinos having hierarchical spectrum is...

    M. Florian BONNET (Laboratoire de Physique Théorique)
    05/03/2008 17:55
    The \mu -> e \gamma and \tau -> l \gamma decay rates are evaluated in the framework of the seesaw model with triplets of fermions. We show that the observation of one of these radiative decays by the new planed experiments would contradict the bounds which arise in this model coming from \mu -> eee and \tau 3l decays, which is an interesting possibility to exclude the model.

  78. 37. Current NuMI/MINOS Oscillation Results
    Prof. Alec Habig (University of Minnesota Duluth)
    05/03/2008 19:35
    The MINOS experiment is now making precise measurements of the $\nu_\mu$ disappearance oscillations seen in atmospheric neutrinos, and will extend our reach towards the so far unseen $\theta_{13}$ by looking for $\nu_e$ appearance in the $\nu_\mu$ beam. It does so by using the intense, well-understood NuMI neutrino beam created at Fermilab and observing it 735 km away at the Soudan Mine in...

    Prof. Ann Nelson (University of Washington)
    06/03/2008 09:15
    A "Chameleon" is a force whose apparent range and strength can depend on the size and density of the source. I discuss how a U(1) gauge force can be chameleonic due to screening from a light charged scalar. Such screening can weaken astrophysical constraints on new gauge bosons, allow a B-L interaction to be strong enough to affect short baseline neutrino oscillations, and change the...

  83. 48. MiniBooNE, LSND, and sterile neutrinos
    Dr Thomas Schwetz-Mangold (CERN)
    06/03/2008 09:35
    I review the interpretation of the LSND signal in terms of sterile neutrino oscillations in the light of MiniBooNE results, considering 1, 2, or 3 sterile neutrinos with eV scale masses. Since no satisfactory fit to the global data is obtained in these cases, I speculate on a non-standard energy dependence of sterile neutrino oscillations, which can significantly improve the fit.

    Dr Ferenc Dalnoki-Veress (Princeton University)
    06/03/2008 10:55
    Borexino is a large volume, real-time, liquid scintillator detector located at the Gran Sasso National Laboratory in Italy. The principal objective of the detector is to measure mono energetic (862 keV) Be-7 neutrinos from the sun present with a count rate of several tens of events per day. Measurement at this level requires an extremely low internal background due to natural radioactivity...

    The observation of high energy neutrinos from cosmic objects is expected to bring us key information about the most energetic processes known in the universe, such as gamma ray bursts and events in the surroundings of supermassive black holes. Their observation could also help us to understand the mechanism for cosmic ray acceleration, a long-standing puzzle. High energy neutrinos may also...

    Recent results obtained by the HARP collaboration on the measurements of the double-differential production cross-section of positive and negative pions in interactions of 3-12 GeV/c protons with nuclear targets from Beryllium to Lead are presented. They cover production at small angles (30-210 mrad) and relatively large momenta up to 8 GeV/c as well as large angles (0.35 - 2.15 rad)...

    Dr Antonio Marrone (Dipartimento di Fisica, Univ. di Bari & INFN Bari)
    07/03/2008 09:10
    A brief introduction to neutrino self-interaction effects in Supernovae (SN) is presented. In the extreme environment of core collapse SNe, the very large neutrino densities induce collective flavor transitions, different from the usual MSW neutrino oscillations in matter. In particular, self-interaction induced neutrino oscillations can be very important for inverted neutrino hierarchy...

  96. 7. LHC test of the see-saw
    Dr Joern Kersten (Abdus Salam ICTP)
    07/03/2008 09:30
    We discuss the prospects for detecting right-handed neutrinos which are introduced in the see-saw mechanism at future colliders. This requires a very accurate cancellation between contributions from different right-handed neutrinos to the light neutrino mass matrix. We search for possible symmetries behind this cancellation and find that they have to include lepton number conservation. Light...

    Dr Silvia Borghi (CERN)
    07/03/2008 11:10
    The CAST (CERN Axion Solar Telescope) experiment is searching for solar axions by their conversion into photons inside the magnet pipe of an LHC dipole. The analysis of the data recorded during the first phase of the experiment with vacuum in the magnet pipes has resulted in the most restrictive experimental limit on the coupling constant of axions to photons. In the second phase, CAST is...

    M. Andrea De Simone (Massachusetts Institute of Technology)
    07/03/2008 17:00
    The set of quantum Boltzmann equations relevant for leptogenesis is derived using non-equilibrium quantum field theory. They manifest memory effects leading to a time-dependent CP asymmetry which depends upon the previous history of the system. This result is particularly relevant in resonant leptogenesis where the asymmetry is generated by the decays of nearly mass-degenerate right-handed...

    The measurement of the energy spectrum above $2.5\cdot 10^{18}$ eV at the Pierre Auger Observatory is presented. Above 20000 events of zenith angle less than $60^\circ$ have been recorded by the surface detector and the acceptance of 7000 km$^2$sr yr, achieved during the construction phase is larger than of previous experiments. The spectral features of the particle flux will be disscused....

    M. Arman Esmaili Taklimi (IPM (Institute for Studies in Theoretical Physics and Mathematics))
    In this talk we introduce a new class of combinations of neutrino mass matrix elements which are invariant under basis transformations. We discuss how these invariants can be used to formulate conditions of vanishing CP-phases (both Majorana and Dirac phases). Also, there is a rich literature on neutrino mass models that are based on certain symmetries that are manifest only in a special...
