Prospects for Supersymmetry at the LHC & Beyond

TL;DR

This paper evaluates the potential for discovering supersymmetry at the LHC and future colliders, considering recent motivations and various models, and discusses experimental strategies and prospects for measurement.

Contribution

It provides a comprehensive analysis of supersymmetry prospects at the LHC and beyond, incorporating recent motivations and exploring different theoretical frameworks.

Findings

Supersymmetry could be discovered through missing energy or long-lived sparticle searches.

Future colliders may be essential if supersymmetry is not found at the LHC.

Measurements could confirm or refute supersymmetry models based on spectrum data.

Abstract

Run 1 of the LHC has provided three new motivations for supersymmetry: the need to stabilize the electroweak vacuum, the mass of the Higgs boson, and the fact that its couplings are Standard Model-like (so far). The prospects for discovering (and measuring) supersymmetry during future runs of the LHC are discussed in the frameworks of the constrained MSSM (CMSSM), models with non-universal soft supersymmetry-breaking contributions to Higgs masses (NUHM1,2) and the phenomenological MSSM with 10 arbitrary soft supersymmetry-breaking parameters (pMSSM10). In addition to the classic searches for missing transverse energy, searches for long-lived charged sparticles may also be promising. If supersymmetry does show up at the LHC, there are good prospects for measurements of the spectrum that can be compared with the indirect indications from other experiments. On the other hand, a higher-energy future circular proton-proton collider may be the best option for discovering supersymmetry if it does not appear at the LHC.
