Standard Model Higgs boson mass from inflation

TL;DR

This paper investigates the viability of Higgs-driven inflation within the Standard Model, determining the Higgs mass range compatible with inflation and showing that key inflationary predictions are largely independent of the Higgs mass.

Contribution

It provides a detailed analysis of one-loop radiative corrections to Higgs inflation and establishes the specific Higgs mass interval where inflation can occur.

Findings

Higgs mass must be between approximately 137 and 185 GeV for inflation

Spectral index n_s is approximately 0.97

Tensor-to-scalar ratio r is approximately 0.0034

Abstract

We analyse one-loop radiative corrections to the inflationary potential in the theory, where inflation is driven by the Standard Model Higgs field. We show that inflation is possible provided the Higgs mass m_H lies in the interval m_min<m_H<m_max, where m_min=[136.7+(m_t-171.2)*1.95]GeV, m_max=[184.5+(m_t-171.2)*0.5]GeV and m_t is the mass of the top quark. Moreover, the predictions of the spectral index of scalar fluctuations and of the tensor-to-scalar ratio practically do not depend on the Higgs mass within the admitted region and are equal to n_s=0.97 and r=0.0034 correspondingly.
