Bounce Inflation Cosmology with Standard Model Higgs Boson

Understand

It is of great interest to connect cosmology in the early universe to the Standard Model of particle physics.

• In this paper, we try to construct a bounce inflation model with the standard model Higgs boson, where the one loop correction is taken into account in the effective potential of Higgs field.
• In this model, a Galileon term has been introduced to eliminate the ghost mode when bounce happens.
• Moreover, due to the fact that the Fermion loop correction can make part of the Higgs potential negative, one naturally obtains a large equation of state(EoS) parameter in the contracting phase, which can eliminate the anisotropy problem.
