Self-shielding effect of a single phase liquid xenon detector for direct dark matter search
A. Minamino, K. Abe, Y. Ashie +41
Liquid xenon is a suitable material for a dark matter search. For future large scale experiments, single phase detectors are attractive due to their simple configuration and scalab…
Right-handed sneutrino dark matter and big-bang nucleosynthesis
Koji Ishiwata, Masahiro Kawasaki, Kazunori Kohri +1
We study the light-element abundances in supersymmetric model where the right-handed sneutrino is the lightest superparticle (LSP), assuming that the neutrino masses are purely Dir…
Observation of TeV Gamma Rays from the Fermi Bright Galactic Sources with the Tibet Air Shower Array
M. Amenomori, X. J. Bi, D. Chen +81
Using the Tibet-III air shower array, we search for TeV gamma-rays from 27 potential Galactic sources in the early list of bright sources obtained by the Fermi Large Area Telescope…
Implications of CDMS II result on Higgs sector in the MSSM
Junji Hisano, Kazunori Nakayama, Masato Yamanaka
We study implications of two dark matter candidate events at CDMS-II on the neutralino dark matter scenario in the supersymmetric standard model, in light of the recent lattice sim…
Density Fluctuations in Thermal Inflation and Non-Gaussianity
Masahiro Kawasaki, Tomo Takahashi, Shuichiro Yokoyama
We consider primordial fluctuations in thermal inflation scenario. Since the thermal inflation drives about 10 -folds after the standard inflation, the time of horizon-exit duri…
Type II-P Supernovae from the SDSS-II Supernova Survey and the Standardized Candle Method
Chris B. D'Andrea, Masao Sako, Benjamin Dilday +24
We apply the Standardized Candle Method (SCM) for Type II Plateau supernovae (SNe II-P), which relates the velocity of the ejecta of a SN to its luminosity during the plateau, to 1…
