Description
It has been shown that the Next-to-Minimal Supersymmetric Standard Model (NMSSM) is a valid theory to describe inflation by Higgs bosons. In this model, the inflaton is a linear combination of the Higgs doublets while the Higgs singlet stabilizes the Higgs potential during inflation. The inflaton has a non-minimal coupling to gravity which appears in the low-energy effective Superpotential. Different from the $\mathbb{Z}_{3}$-invariant NMSSM an additional bilinear $\mu$ parameter is introduced which changes the phenomenology at the electroweak scale.
We investigate the impact of this inflation-inspired model on low-energy physics with the focus set on vacuum stability and Higgs phenomenology. We explore the extended parameter space and point out differences compared to the standard $\mathbb{Z}_{3}$-invariant NMSSM due to the additional $\mu$ term. Thereby, we take into account various experimental constraints.
