Plateau Inflation in SUGRA-MSSM

Understand

We explored a Higgs inflationary scenario in the SUGRA embedding of the MSSM in Einstein frame where the inflaton is contained in the $SU(2)$ Higgs doublet.

• We include all higher order non-renormalizable terms to the MSSM superpotential and an appropriate K\"ahler potential which can provide slow-roll inflaton potential in the $D-$flat direction.
• In this model, a plateau-like inflation potential can be obtained if the imaginary part of the neutral Higgs acts as the inflaton.
• The inflationary predictions of this model are consistent with the latest CMB observations.
