  1. 45. Tracking performance in V0 reconstruction with first data at LHCb
    M. Sascha Stahl (Physikalisches Institut Heidelberg)
    10/03/2010 19:10
    The reconstruction of $K^0_S$ and $\Lambda$ resonances is a crucial test of the performance of the LHCb tracking detectors, the reconstruction software and the status of the alignment of the LHCb spectrometer. We will present first results towards a measurement of the V0 production rate based on data taken at a center of mass energy of 900GeV in December 2009 with the LHCb experiment.

  2. 46. Measuring the J/Psi Production Cross Section with CMS
    Dr Luca Martini (Pisa)
    10/03/2010 19:17
    The workflow of the measurement of the Jpsi cross section in the di-muon decay channel with CMS at the LHC will be given, with a particular emphasis in the description of the determination of the muon detection efficiency and acceptance.

  3. 33. Strategy for an early observation of the $ZZ^(*)$ di-boson production in four-lepton final states
    M. Daniele Trocino (Università di Torino, INFN Torino)
    10/03/2010 19:25
    The study of the production of two Z bosons at the TeV scale constitutes an important test of the Standard Model and it is a necessary step towards the discovery of new physics and new particles like the Higgs boson. We investigate the CMS potential for the observation and study of pp-> ZZ->4l reaction at LHC center of mass energies, using fully simulated signal and background samples. It is...

  4. 77. Optimization of the electron reconstruction and identification in ATLAS experiment and implications on the Higgs to 4 electrons analysis.
    Mme Fany Dudziak (Laboratoire de l'Accélérateur Linéaire)

    Experiment
    YSF (Young Scientists Forum)
    The search for the Higgs boson will be one of the main issues in the next year in the ATLAS detector. The H->ZZ*->4e channel in particular, is a very promizing channel to discover the Higgs for masses above 130 GeV with a clean electron signal. The electron reconstruction and identification plays here a key role. Since the CSC note published 2 years ago a lot of work as been done in order to...

  5. 36. The ATLAS discovery reach for SUSY models with early data
    Mlle Janet Dietrich (University of Freiburg)
    10/03/2010 19:39
    The search for physics beyond the Standard Model (BSM) is one of the most important goals for the general purpose detector ATLAS at the Large Hadron Collider at CERN. Already with early LHC data, the ATLAS experiment should be sensitive to discover physics beyond the Standard Model. In this talk I summarize the prospects of the ATLAS experiment to find experimental evidence for Supersymmetry...

  6. 5. New Physics bounds from CKM-unitarity
    Martin Gonzalez-Alonso (Universidad de Valencia)
    10/03/2010 19:46
    Using a effective Lagrangian approach we show how the bounds to the new operators that come from high energy data can be improved with the inclusion of the experimental information of the CKM-universality, a low energy observable. We assume U(3)^5 invariance, although some remarks will be done about the general case, with non-U(3)^5 invariant operators.

  7. 64. Muon identification in the LHCb experiment
    M. Xabier Cid Vidal (USC - IGFAE)
    10/03/2010 19:53
    Experiment
    YSF (Young Scientists Forum)
    Several key measurements of the LHCb experiment rely on the efficient identification of muons. Examples of these are the search for the rare decay Bs->mumu and the study of the angular distributions of the decay B0>K*mumu. A summary of the LHCb muon identification strategy is presented, covering both the baseline method, and also alternative approaches presently under development. First...

  8. 114. Sensitivity of T2KK to NSI in propagation
    Mlle Haruna Oki (Tokyo Metropolitan University)
    10/03/2010 20:00
    We study sensitivity to the non-standard interaction in neutrino propagation of the T2KK neutrino long baseline experiment, assuming only the non-zero electron and tau neutrino components epsilon_{ee}, epsilon_{e tau}, epsilon_{tau tau} of the non-standard matter effect, and taking into account the atmospheric neutrino constraint on these parameters. We found that T2KK can restrict the...

  9. 73. The fine tuning guide for SUSY searches
    M. Sebastian Cassel Cassel (Oxford University)
    10/03/2010 20:07
    Theory
    YSF (Young Scientists Forum)
    Low energy supersymmetry can be theoretically motivated as a solution to the hierarchy problem of the Standard Model if the superpartner states are not too heavy. The non-observation of SUSY and precision tests then introduces some tension in the attempt for naturalness. I will present a study of the amount of fine tuning at 2-loop order in the constrained MSSM and discuss which regions of the...
