Sneutrino Chaotic Inflation and Landscape

Understand

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.
