17. Dark matter detection in the BMSSM

Dr Nicolás BERNAL (CFTP - IST)

11/03/2010 08:30

The addition of non-renormalizable terms involving the Higgs fields to the MSSM (BMSSM) ameliorates the little hierarchy problem of the MSSM. For neutralino dark matter, new regions for which the relic abundance of the LSP is consistent with WMAP (as the bulk region and the stop coannihilation region) are now permitted. In this framework, we analyze in detail the direct dark matter detection...

48. Recent Results from CDMS

Dr Lauren Hsu (Fermi National Accelerator Laboratory)

11/03/2010 08:55

I will present the search for WIMP interactions with the final data collected by the CDMSII experiment. CDMS has pioneered the use of ionization and athermal phonon signals to discriminate between candidate (nuclear recoil) and background (electron recoil) events in Ge crystals cooled to ~ 50 mK. Our timing, yield, and position information allows us to maximize our discovery potential by...

42. First EDELWEISS-II results

Dr Silvia Scorza (Institut de Physique Nucléaire de Lyon (IPNL))

11/03/2010 09:15

The EDELWEISS-II collaboration has performed a direct search for WIMP dark matter with an array of ten 400 g heat-and-ionization cryogenic detectors equipped with interleaved electrodes for the rejection of near-surface events. Six months of continuous operation at the Laboratoire Souterrain de Modane have been achieved. The observation of one nuclear recoil candidate above 20 keV in an...

20. Determining WIMP parameters from direct detection experiments

Dr Anne Green (University of Nottingham)

11/03/2010 09:35

Theory

I will discuss the information on the WIMP parameters (mass and cross-section) which can be extracted from current and upcoming direct detection experiments. In particular I will discuss the effects of astrophysical uncertainties (in the local WIMP density and velocity distribution).

35. SO(10) Dark Matter and Electroweak Symmetry Breaking

Dr Kristjan Kannike (NICPB, Estonia)

11/03/2010 09:55

Theory

Ordinary

We consider a minimal model of GUT scalar dark matter with one complex scalar singlet and one 'inert' doublet from the 16 of non-SUSY SO(10). Both dark matter abundance and direct detection cross section are dominated by the new soft coupling between the SM Higgs boson, the singlet and the doublet. The soft coupling can be large without violating perturbativity below the GUT scale. The...

52. Status of the T2K experiment

M. Kodai Matsuoka (Kyoto University)

11/03/2010 10:30

T2K is a long baseline neutrino oscillation experiment which aims to precisely measure the oscillation parameters associated with \nu_{\mu} disappearance and to search for \nu_{e} appearance. It utilizes the J-PARC proton synchrotron to produce the muon neutrino beam, which is measured by the near detectors and the Super-Kamiokande detector. The T2K neutrino beamline and the near detectors...

3. Recent results from MiniBooNE: update on low-energy excess and cross-section measurements

Dr Bari Osmanov (University of Florida)

11/03/2010 10:50

Experiment

MiniBooNE is a neutrino oscillation experiment located in Fermilab, USA. Its primary goal was to verify or reject neutrino oscillations as the source of the excess of events observed by the LSND experiment at LANL From its start of operation in 2002, MiniBooNE has reported many interesting scientific results including low-energy excess in neutrino mode and various cross-section...

57. SciBooNE and other neutrino cross section measurements

Prof. Masashi Yokoyama (University of Tokyo)

11/03/2010 11:10

Accurate knowledge of neutrino cross section around 1 GeV energy is important for long baseline neutrino oscillation experiments. In this talk, latest results from SciBooNE, a neutrino cross section experiment at Fermilab, will be presented together with some of related results from other experiments.
