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…
