Description
We consider the supersymmetric version of the Higgs inflation scenario with non-minimal coupling in 4D Jordan frame supergravity. We find that there occurs a tachyonic instability along the direction of the accompanying non-inflaton field in generic Jordan frame supergravity models. We find that a higher order correction to the Jordan frame function solves the tachyonic mass problem and show that the necessary correction can be naturally generated by the heavy thresholds without spoiling the slow-roll conditions. We discuss the implication of the Higgs inflation on NMSSM.
