The authors' main claim 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).

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}.

The paper

Original 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}.

Global fits of GUT-scale SUSY models with GAMBIT

Global fits to the CMSSM, NUHM1 and NUHM2 exclude stau co-annihilation in the CMSSM at more than 95% confidence and identify stop co-annihilation as a surviving, LHC-relevant dark matter mechanism in all three models.
Muon g-2 vs LHC in Supersymmetric Models

Reinterpreting ATLAS searches for electroweak supersymmetric particles, the authors show the LHC already excludes part of the supersymmetric parameter space that would explain the muon g-2 anomaly.

Combining thermal freeze-out, gravitino freeze-in, and UV gravitino production in Spread Supersymmetry with a wino LSP leaves squarks between about 100 and 10,000 TeV, so gluinos can be light enough for the LHC and lo...
Upper bounds on sparticle masses from naturalness or how to disprove weak scale supersymmetry

With a fine-tuning threshold of 30, naturalness implies a higgsino mass below 350 GeV and a gluino mass below 4 to 7 TeV, giving experimenters concrete targets for confirming or excluding weak-scale supersymmetry.

Scanning the MSSM against Higgs, flavor, relic-density, and direct-detection constraints leaves a mostly Bino-like neutralino dark matter candidate whose annihilation runs through Z and Higgs resonances and co-annihilations.
