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...

T2K 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...

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...

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.

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,...

Single-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...

We 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...

While 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...
