Strongly Interacting Gauge Mediation at the LHC

TL;DR

This paper explores the signatures of strongly interacting gauge mediation (SIGM) of supersymmetry breaking at the LHC, highlighting how to distinguish it from conventional models through high transverse momentum lepton counts.

Contribution

It introduces the phenomenological signatures of SIGM at the LHC and proposes a method to differentiate it from standard gauge mediation models.

Findings

SIGM predicts a light gravitino of mass less than about 10 eV.

High $P_T$ lepton counting can discriminate SIGM from conventional gauge mediation.

Potential early LHC signatures of SIGM are identified.

Abstract

Strongly interacting gauge mediation (SIGM) of supersymmetry breaking is very attractive, since it naturally predicts a light gravitino of mass $\lsim{\cal O}(10)$ eV, which causes no cosmological problem. We discuss various signatures of the SIGM in the early stage (a low integrated luminosity period) of the LHC experiments. We show, in particular, a possible way to discriminate it from the conventional gauge mediation by counting the number of high $P_{\rm T}$ leptons.
