Correlation between the Higgs Decay Rate to Two Photons and the Muon g - 2

TL;DR

This paper explores how an increased Higgs decay rate to two photons correlates with the muon g-2 anomaly within minimal supersymmetry, suggesting specific particle mass configurations that explain both phenomena.

Contribution

It demonstrates that a 40% enhancement in Higgs to gamma gamma decay rate naturally aligns with the muon g-2 anomaly in a minimal supersymmetric framework with specific slepton and gaugino mass conditions.

Findings

Enhanced h → gamma gamma correlates with muon g-2 anomaly.

Light stau and Bino are predicted, with heavy higgsinos.

Small deviations in other Higgs decay channels and lepton universality violations.

Abstract

In the context of minimal supersymmetry with slepton mass universality we find that an enhancement in h \rightarrow gamma gamma by at least 40%, as hinted by present data, implies a deviation of the muon anomalous magnetic moment by exactly the right amount to explain the observed anomaly. The enhancement in h \rightarrow gamma gamma selects a light stau with large left-right mixing, a light Bino, and heavy higgsinos. The corresponding parameters are compatible with thermal dark matter, predict small deviations in h \rightarrow Z gamma and h \rightarrow tau tau, and measurable violations of lepton universality.
