Sneutrino chaotic inflation and landscape

Hitoshi Murayama, Kazunori Nakayama, Fuminobu Takahashi, Tsutomu T. Yanagida

Abstract

The most naive interpretation of the BICEP2 data is the chaotic inflation by an inflaton with a quadratic potential. When combined with supersymmetry, we argue that the inflaton plays the role of right-handed scalar neutrino based on rather general considerations. The framework suggests that the right-handed sneutrino tunneled from a false vacuum in a landscape to our vacuum with a small negative curvature and suppressed scalar perturbations at large scales.
