Large U_{e3} and Tri-bimaximal Mixing
Srubabati Goswami, Serguey Petcov, Shamayita Ray +1
We investigate in a model-independent way to what extent one can perturb tri-bimaximal mixing in order to generate a sizable value of |U_{e3}|, while at the same time keeping solar…
Dipolar Dark Matter
Eduard Masso, Subhendra Mohanty, Soumya Rao
If dark matter (DM) has non-zero direct or transition, electric or magnetic dipole moment then it can scatter nucleons electromagnetically in direct detection experiments. Using th…
Visible and Dark Matter Genesis and Cosmic Positron/Electron Excesses
Pei-Hong Gu, Utpal Sarkar, Xinmin Zhang
Dark and baryonic matter contribute comparable energy density to the present Universe. The dark matter may also be responsible for the cosmic positron/electron excesses. We connect…
Double Type-II Seesaw, Baryon Asymmetry and Dark Matter for Cosmic e^\pm Excesses
Pei-Hong Gu, Hong-Jian He, Utpal Sarkar +1
We construct a new realization of type-II seesaw for neutrino masses and baryon asymmetry by extending the standard model with one light and two heavy singlet scalars besides one H…
Annihilating Leptogenesis
Pei-Hong Gu, Utpal Sarkar
Leptogenesis is usually realized through decays of heavy particles. In this article we consider another possibility of generating a lepton asymmetry through annihilations of heavy…
Use of Transverse polarization to probe R-parity violating supersymmetry at ILC
Rohini M Godbole, Santosh Kumar Rai, Saurabh D Rindani
In supersymmetric theories with R-parity violation, squarks and sleptons can mediate Standard Model fermion-fermion scattering processes. These scalar exchanges in e+e- initiated r…
