Discovery potential for SUSY at a high luminosity upgrade of LHC14

TL;DR

This paper evaluates the discovery potential of the high-luminosity LHC at 14 TeV for supersymmetry, projecting the mass reach for gluinos, squarks, and charginos with increased luminosity.

Contribution

It provides updated projections for SUSY detection reach at LHC14 with high luminosity, focusing on the mSUGRA/CMSSM model and specific decay channels.

Findings

LHC14 with 300 fb^{-1} can detect gluinos up to ~3.2 TeV.

LHC14 with 3000 fb^{-1} can detect gluinos up to ~3.6 TeV.

Reach for chargino-neutralino detection extends to ~2.6 TeV with high luminosity.

Abstract

After completion of the LHC8 run in 2012, the plan is to upgrade the LHC for operation close to its design energy sqrt{s}=14 TeV, with a goal of collecting hundreds of fb^{-1} of integrated luminosity. The time is propitious to begin thinking of what is gained by even further LHC upgrades. In this report, we compute an LHC14 reach for SUSY in the mSUGRA/CMSSM model with an anticipated high luminosity upgrade. We find that LHC14 with 300 (3000) fb^{-1} has a reach for SUSY via gluino/squark searches of m(gluino)\sim3.2 TeV (3.6 TeV) for m(squark)\sim m)gluino), and a reach of m(gluino)\sim1.8 TeV (2.3 TeV) for m(squark)>> m(gluino). In the case where m(squark)>> m(gluino), then the LHC14 reach for chargino-neutralino production with decay into the Wh+MET final state reaches to m(gluino)\sim2.6 TeV for 3000 fb^{-1}.
