Discovering SUSY in the First LHC Run

TL;DR

This paper assesses the potential of the first LHC run at 7 TeV with 1/fb to discover Supersymmetry, using parameter fits constrained by experimental and cosmological data.

Contribution

It provides a detailed analysis of SUSY discovery prospects at the LHC considering constrained MSSM and NUHM1 models with current experimental constraints.

Findings

Large regions of SUSY parameter space are accessible at early LHC run.

The analysis combines electroweak, (g-2)_mu, B-physics, and cosmological constraints.

Early LHC data could potentially discover SUSY in favored parameter regions.

Abstract

We analyze the potential of the first LHC physics run, assuming 1/fb at sqrt[s] = 7 TeV, to discover Supersymmetry (SUSY). The results are based on SUSY parameter fits following a frequentist approach. They include the experimental constraints from electroweak precision data, (g-2)_mu, B-physics and cosmological data. The two SUSY models under consideration are the constrained MSSM (CMSSM) with universal soft supersymmetry-breaking mass parameters, and a model with common non-universal Higgs mass parameters in the superpotential (NUHM1). We find that large parts of the regions preferred at the 68% C.L. are accessible to early LHC running.
