Supersymmetry: The Final Countdown

TL;DR

This paper discusses the prospects of discovering supersymmetry at the LHC, focusing on the minimal supersymmetric standard model (MSSM) with gravity-mediated SUSY breaking, and how gaugino mass spectra can help identify SUSY models.

Contribution

It analyzes how gaugino mass ratios can serve as signatures to distinguish simple SUSY breaking schemes in string-inspired models at the LHC.

Findings

Gaugino mass ratios can help identify SUSY breaking mechanisms.

The MSSM with gravity-mediated SUSY breaking is a promising scenario for early LHC discovery.

Properties of the gluino/neutralino spectrum are key to understanding SUSY models.

Abstract

There is hope that the Large Hadron Collider (LHC) at CERN will tell us about the fate of supersymmetry at the TeVscale. Therefore we might try to identify our expectations for the discovery of SUSY, especially in the first years of operation of this machine. In this talk we shall concentrate on the simplest SUSY scheme: the MSSM with SUSY broken in a hidden sector mediated by interactions of gravitational strength (gravity-, modulus and mirage-mediation). Such a situation might be favoured in a large class of string inspired models. There is a good chance to identify such simple schemes by knowing the properties of the gaugino mass spectrum such as the gluino/neutralino mass ratios.
