New Model of Inflation with Non-minimal Derivative Coupling of Standard Model Higgs Boson to Gravity

TL;DR

This paper introduces a unique non-minimal derivative coupling of the Standard Model Higgs boson to gravity that enables successful inflation without extra degrees of freedom or problematic quantum corrections.

Contribution

It proposes a novel coupling mechanism that allows the Higgs boson to drive inflation while maintaining theoretical consistency and minimal quantum corrections.

Findings

Reproduces a successful inflationary background with Standard Model parameters

Propagates no additional degrees of freedom beyond General Relativity

Remains stable against dangerous quantum corrections

Abstract

In this letter we show that there is a unique non-minimal derivative coupling of the Standard Model Higgs boson to gravity such that: it propagates no more degrees of freedom than General Relativity sourced by a scalar field, reproduces a successful inflating background within the Standard Model Higgs parameters and, finally, does not suffer from dangerous quantum corrections.
