The Lightest Higgs Boson Mass in Pure Gravity Mediation Model

TL;DR

This paper predicts the lightest Higgs boson mass in a minimal supersymmetric model with pure gravity mediation, linking it to dark matter density and baryogenesis, and constrains its upper limit.

Contribution

It provides a specific upper bound on the Higgs boson mass in the pure gravity mediation model considering dark matter and leptogenesis constraints.

Findings

Higgs mass predicted below 132 GeV.

Upper limit of 128 GeV if thermal leptogenesis is assumed.

Relations between Higgs mass and gaugino masses discussed.

Abstract

We discuss the lightest Higgs boson mass in the minimal supersymmetric Standard Model with "pure gravity mediation". By requiring that the model provides the observed dark matter density, we find that the lightest Higgs boson is predicted to be below 132GeV. We also find that the upper limit on the lightest Higgs boson mass becomes 128GeV, if we further assume thermal leptogenesis mechanism as the origin of baryon asymmetry of universe. The interrelations between the Higgs boson mass and the gaugino masses are also discussed.
