M. Hajime Ishimori (Niigata university)11/03/2010 18:05YSF (Young Scientists Forum)We have studied $\Delta(54)$ flavor model for leptons and sleptons. The tri-bimaximal mixing can be reproduced for arbitrary neutrino masses if vacuum alignments of scalar fields are guaranteed. The deviation from the tri-bimaximal mixing of leptons is predicted. The predicted upper bound for $\sin\theta_{13}$ is 0.06. The magnitude of $\sin\theta_{23}$ could be deviated from the maximal...Go to contribution page

Joshua Albert (Duke University)11/03/2010 18:13T2K is a long baseline neutrino beam experiment scheduled to begin operation in 2009. The energy of the muon neutrino beam from JPARC and the distance (295 km) to the far detector (Super-Kamiokande) have been chosen to maximize sensitivity to electron neutrino appearance through neutrino oscillation. By identifying this oscillation signal from among backgrounds, including NC pi0 production, a...Go to contribution page

Lorenzo Ubaldi (University of California, Santa Cruz)11/03/2010 18:21TheoryYSF (Young Scientists Forum)Active Galactic Nuclei (AGN) are believed to reside in the center of massive dark matter (DM) halos. The energetic electrons and protons in AGN jets crossing regions of high DM density can scatter off the DM particles, producing gamma rays in the final state. If the DM is a weakly interacting massive particle (WIMP), its mass is such that the final state gamma-ray emission will be almost...Go to contribution page

M. Julien Billard (LPSC Grenoble)11/03/2010 18:29ExperimentYSF (Young Scientists Forum)Directional detection of galactic Dark Matter is a promising search strategy for discriminating geniune WIMP events from background ones. I will first review technical progress on directional detectors and present a comprehensive analysis method. The goal is to identify galactic Dark Matter by proving its correlation with the solar motion.Go to contribution page

Mlle Keiko Nagao (Nagoya University)11/03/2010 18:37TheoryYSF (Young Scientists Forum)Weakly interacting massive particle (WIMP) is a hopeful candidate of dark matter. In order to calculate the abundance of WIMP in the universe, its annihilation cross section is needed. We calculate the one-loop correction to the annihilation cross section in case that the correction is possible to be large. When a exchanged boson has negligible mass compared to the mass of annihilating WIMP,...Go to contribution page

M. Christopher Jones (Massachusetts Institute of Technology)11/03/2010 18:45ExperimentSingle-detector reactor-based oscillation experiments, like the first run of Double Chooz, require accurate predictions of the reactor flux. In this talk I present results from the deterministic lattice code DRAGON, which is used to simulate the nuclear fission rates of uranium and plutonium isotopes. These fission rates are then convoluted with the inverse beta decay cross section to...Go to contribution page

M. Alexey Lokhov (Graduate student)11/03/2010 18:53We consider the process of neutrino radiative transition between different mass states in medium. The neutrino wave functions, used in calculations of the process rate and power, are obtained within the method of exact solutions of the modified Dirac equation in medium. The contribution of magnetic moment induced transition is analyzed in details. It is shown how the background matter could...Go to contribution page

Dr Alexander Knochel (Uni Freiburg)11/03/2010 19:01While the Higgs Bosons of the Standard Model or MSSM have so far eluded direct detection, BSM models should address the strong hints pointing towards particle dark matter around or below the TeV scale. Based on a model [0805.1379v2] and parton level simulations in O'Mega/Whizard [0909.5330v1], I argue that thermal CDM candidates in alternative warped EWSB scenarios potentially exhibit a quite...Go to contribution page
