LHC discovery potential for supersymmetry with \sqrt{s}=7 TeV and 5-30 fb^{-1}

TL;DR

This paper evaluates the Large Hadron Collider's potential to discover supersymmetry at 7 TeV with 5-30 fb^{-1} of data, providing detailed mass reach estimates within the mSUGRA framework.

Contribution

It extends previous SUSY reach studies to higher luminosities and optimizes detection strategies for different mass scenarios within the minimal supergravity model.

Findings

LHC can discover gluinos up to 1.6 TeV with 30 fb^{-1} for certain mass conditions.

Discovery reach varies with gluino and squark mass hierarchies.

Quantitative mass reach estimates for different luminosities are provided.

Abstract

We extend our earlier results delineating the supersymmetry (SUSY) reach of the CERN Large Hadron Collider operating at a centre-of-mass energy \sqrt{s}=7 TeV to integrated luminosities in the range 5 - 30 fb^{-1}. Our results are presented within the paradigm minimal supergravity model (mSUGRA or CMSSM). Using a 6-dimensional grid of cuts for the optimization of signal to background ratio -- including missing E_T-- we find for m(gluino) \sim m(squark) an LHC 5\sigma SUSY discovery reach of m(gluino) \sim 1.3,\ 1.4,\ 1.5 and 1.6 TeV for 5, 10, 20 and 30 fb^{-1}, respectively. For m(squark)>> m(gluino), the corresponding reach is instead m(gluino)\sim 0.8,\ 0.9,\ 1.0 and 1.05 TeV, for the same integrated luminosities.
