Heavier Higgs Particles: Indications from Minimal Supersymmetry

TL;DR

This paper analyzes recent Higgs data to infer the possible mass range of heavier Higgs particles in Minimal Supersymmetry, suggesting they could be between 320 and 360 GeV.

Contribution

It provides a novel fit of Higgs couplings to experimental data to constrain the mass of heavier Higgs bosons in Minimal Supersymmetry.

Findings

Heavier Higgs masses between 320 and 360 GeV are compatible with current data.

Values of tan(beta) between 1 and 6 are consistent with observations.

Larger Higgs masses are compatible at the 1sigma level.

Abstract

We use the most recent data on the Higgs-like resonance h observed at 125 GeV to derive information about the mass of the heavier Higgs particles predicted by Minimal Supersymmetry. We treat as independent parameters the couplings of h to top quark, beauty and massive vector bosons and, in this three dimensional space, we locate the point realizing the best fit to data and compare it to the position of the Standard Model point and to the region of coupling values accommodating heavier Higgs particles in Minimal Supersymmetry. We conclude that mass values 320< M_H< 360 GeV are compatible at 2sigma with the best fit of couplings to present data, larger values being compatible at the 1sigma level. Values of 1< tan(beta)< 6 are compatible with data.
