The W boson mass weighs in on the non-standard Higgs

TL;DR

The paper explores how the recent high-precision W boson mass measurement impacts models with a non-standard Higgs, suggesting enhanced Higgs-gauge boson coupling and implications for new physics phenomena.

Contribution

It demonstrates that the W mass measurement constrains non-standard Higgs models, requiring specific coupling enhancements compatible with dynamical models like dilaton, Technicolor, and glueball Higgs.

Findings

Enhanced Higgs-gauge boson coupling by 3-10%.

Composite scale between 2 and 3 TeV.

Potential explanation for muon g-2 anomaly.

Abstract

We consider the implications of the CDF collaboration high-precision measurement of the W boson mass on models with a non-standard Higgs. We show that this requires an enhancement of 3-10% in the non-standard Higgs coupling to the gauge bosons. This is naturally accommodated in dynamical models such as the dilaton Higgs, the Technicolor and glueball Higgs. The needed composite scale between 2 and 3 TeV can also explain the muon g-2 anomaly, as well as possible violations of lepton flavour universality.
