Adiabatic density perturbations and matter generation from the MSSM
Kari Enqvist, Shinta Kasuya, Anupam Mazumdar
We propose that the inflaton is coupled to ordinary matter only gravitationally and that it decays into a completely hidden sector. In this scenario both baryonic and dark matter o…
Surface reheating as a new paradigm
Anupam Mazumdar, Kari Enqvist, Shinta Kasuya
In this talk we briefly review the standard idea of reheating and then present a new paradigm of reheating the Universe through surface evaporation.
Inflatonic Solitons In Running Mass Inflation
Kari Enqvist, Shinta Kasuya, Anupam Mazumdar
The inflaton condensate associated with a global symmetry can fragment into quasistable Q balls, provided the inflaton oscillations give rise to an effective equation of state with…
Reheating as a surface effect
Kari Enqvist, Shinta Kasuya, Anupam Mazumdar
We describe a new mechanism for reheating the Universe through evaporation of a surface charge of a fragmented inflaton condensate. We show that for a range of Yukawa coupling of t…
Affleck-Dine baryogenesis and the Q-ball dark matter in the gauge-mediated SUSY breaking
S. Kasuya
We consider the Affleck-Dine baryogenesis comprehensively in the minimal supersymmetric standard model with gauge-mediated supersymmetry breaking. Considering the high temperature…
