Bounce Inflation Cosmology with Standard Model Higgs Boson

TL;DR

This paper proposes a bounce inflation model using the Standard Model Higgs boson, incorporating quantum corrections and Galileon terms to address ghost modes and anisotropy, leading to a nearly scale-invariant spectrum.

Contribution

It introduces a novel bounce inflation model with the Higgs field, including one-loop corrections and a Galileon term, to resolve ghost issues and anisotropy in early universe cosmology.

Findings

The model achieves a ghost-free bounce with the Higgs field.

It naturally addresses the anisotropy problem during contraction.

The post-bounce phase produces a nearly scale-invariant power spectrum.

Abstract

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. After the bounce, the model can drive the universe into the standard higgs inflation phase, which can generate nearly scale-invariant power spectrum.
