An alternative heavy Higgs mass limit

TL;DR

This paper proposes a non-perturbative renormalization approach for the Higgs sector, allowing for a very heavy Higgs boson (over 1 TeV) to be a narrow resonance, challenging conventional mass limits.

Contribution

It introduces an alternative non-perturbative renormalization scheme where the Higgs mass does not directly indicate observable interaction strength.

Findings

Higgs could be heavier than 1 TeV and still be a narrow resonance

The new approach decouples Higgs mass from interaction measures

Challenges traditional perturbative mass bounds

Abstract

After commenting on the present value of the Higgs particle mass from radiative corrections, we explore the phenomenological implications of an alternative, non-perturbative renormalization of the scalar sector where the mass of the Higgs particle does not represent a measure of observable interactions at the Higgs mass scale. In this approach the Higgs particle could be very heavy, even heavier than 1 TeV, and remain nevertheless a relatively narrow resonance.
