Supersymmetric fd-hybrid inflation

Research output: Contribution to conferencePaperpeer-review

Abstract

We present Fa-inflation, a variant of supersymmetric F-term hybrid inflation with a subdominant D-term, which controls the decay of heavy gauge-sector fields produced during preheating after inflation. Late decays of these particles give rise to an entropy release and therefore to dilution of gravitinos which would otherwise be in conflict with big-bang-nucleosynthesis. After inflation, the inflaton acquires a vacuum expectation value of TeV-scale, which gives rise to the μ-term of the MSSM as well as to Te V-scale Majorana masses for right-handed neutrinos. Baryogenesis takes place through thermal resonant leptogenesis.
