Early Higgs Hints for Non-Minimal Supersymmetry

TL;DR

This paper explores how Higgs coupling measurements can help distinguish supersymmetric models from the Standard Model, highlighting current data preferences and conditions for future model testing.

Contribution

It identifies the current Higgs coupling preferences and provides a simple condition to test non-minimal supersymmetric models against future data.

Findings

Current data favors suppressed bottom and enhanced top quark couplings.

Minimal supersymmetry faces tension in achieving these couplings for tan beta > 1.

A straightforward condition is proposed to access the preferred coupling region.

Abstract

We discuss the role that Higgs coupling measurements can play in differentiating supersymmetric extensions of the Standard Model. Fitting current LHC data to the Higgs couplings, we find that the likelihood fit shows a preference in the direction of suppressed (enhanced) bottom (top) quark couplings. In the minimal supersymmetric Standard Model, we demonstrate that for tan beta > 1, there is tension in achieving such fermion couplings due to the structure of the Higgs quartic couplings. In anticipation of interpreting supersymmetric models with future data, we determine a single straightforward condition required to access the region of coupling space preferred by current data.
