Higgs mass from cosmological and astrophysical measurements

TL;DR

This paper constrains the Higgs boson mass during inflation by fitting inflationary models to cosmological data, revealing how non-minimal coupling affects inflationary parameters and the Higgs mass estimate.

Contribution

It provides the first direct constraints on the Higgs mass during inflation considering non-minimal coupling effects using cosmological observations.

Findings

Higgs mass during inflation estimated at approximately 144 GeV with uncertainties.

Non-minimal coupling significantly alters inflationary parameters compared to standard inflation.

Inflationary observables are constrained by fitting to WMAP5+BAO+SN data.

Abstract

For a robust interpretation of upcoming observations from Planck and LHC experiments it is imperative to understand how the inflationary dynamics of a non-minimally coupled Higgs scalar field may affect the degeneracy of the inflationary observables. We constrain the inflationary observables and the Higgs boson mass during observable inflation by fitting the the Higgs inflationary potential directly to WMAP5+BAO+SN data. We obtain a Higgs mass a value of 143.73+14.97/-6.31 GeV at 95% CL for the central value of top quark mass. We also show that the inflation driven by a non-minimally coupled scalar field leads to significant changes of the inflationary parameters when compared with the similar constraints from the standard inflation.
