The Higgs Boson Mass in Gauge-Mediated Supersymmetry-Breaking Models with Generalized Messenger Sectors

TL;DR

This paper investigates the mass of the lightest Higgs boson in generalized gauge-mediated supersymmetry-breaking models with diverse messenger sectors, predicting a maximum Higgs mass of 132 GeV, which can be tested at collider experiments.

Contribution

It extends gauge-mediated SUSY-breaking models to include more general messenger sectors and calculates the resulting upper bound on the lightest Higgs mass.

Findings

Maximum Higgs mass is 132 GeV at $\Lambda=100$ TeV.

Predictions are testable at upgraded Tevatron.

General messenger sectors influence Higgs mass bounds.

Abstract

The lighter neutral scalar Higgs mass is examined in gauge-mediated supersymmetry-breaking models in which the messenger sector responsible for SUSY breaking is allowed to involve more general sets of $SU(3) \otimes SU(2) \otimes U(1)$ multiplets than those contained in the SU(5) $5 + \bar{5}$ or $10 + \bar{10}$ multiplets. The largest mass for the lighter scalar Higgs is found to be 132 GeV when the breaking parameter $\Lambda$ is taken to be 100 TeV\@. Thus the predictions for the lightest Higgs mass can be tested at the upgraded Tevatron runs for these general classes of GMSB models.
