Disappearing inflaton potential

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Inflaton potential may disappear by heavy field dynamics I. Chaotic inflation in SUGRA - Mass parameter is promoted to be a dynamical field: S - <S> ≠ 0 during inflation & <S> = 0 after inflation, and then inflaton becomes (almost) massless. => Dark matter / dark radiation / searched by some experiments II. New inflation in SUGRA - Inflaton may return to the origin after reheating and rolls down to the electroweak vacuum => Inflaton can be MSSM Higgs field.
