How to Put a Heavier Higgs on the Lattice

TL;DR

This paper investigates how the cutoff dependence affects the Higgs mass bounds in the Standard Model's scalar sector, using large N calculations to suggest a potential 30% increase in the triviality bound, reaching about 850 GeV.

Contribution

It introduces large N and preliminary N=4 calculations to refine the Higgs mass triviality bound considering cutoff effects.

Findings

Potential 30% increase in the Higgs triviality bound

Bound estimate raised to approximately 850 GeV

Large N calculations provide new insights into cutoff dependence

Abstract

The cutoff dependence of the Scalar Sector of the Minimal Standard Model can result in an increase of the existing triviality bound estimates of the Higgs mass. We present a large $N$ calculation and some preliminary N=4 results that suggest that the increase can be as large as 30%, resulting to a bound of about 850 G eV.
