Global fits of the cMSSM including the first LHC and XENON100 data

TL;DR

This paper updates the global fits of the cMSSM using recent LHC and XENON100 data, showing that current direct detection experiments exclude the Focus Point region and future experiments will probe most of the remaining parameter space.

Contribution

It provides the first comprehensive global fit of the cMSSM incorporating the latest collider and direct detection data, accounting for astrophysical and hadronic uncertainties.

Findings

Focus Point region is robustly ruled out by current data.

Upcoming ton-scale experiments will test nearly all favored parameter space.

Compatibility between Bayesian and Frequentist analyses has increased.

Abstract

We present updated global fits of the constrained Minimal Supersymmetric Standard Model (cMSSM), including the most recent constraints from the ATLAS and CMS detectors at the LHC, as well as the most recent results of the XENON100 experiment. Our robust analysis takes into account both astrophysical and hadronic uncertainties that enter in the calculation of the rate of WIMP-induced recoils in direct detection experiment. We study the consequences for neutralino Dark Matter, and show that current direct detection data already allow to robustly rule out the so-called Focus Point region, therefore demonstrating the importance of particle astrophysics experiments in constraining extensions of the Standard Model of Particle Physics. We also observe an increased compatibility between results obtained from a Bayesian and a Frequentist statistical perspective. We find that upcoming ton-scale direct detection experiments will probe essentially the entire currently favoured region (at the 99% level), almost independently of the statistical approach used. Prospects for indirect detection of the cMSSM are further reduced.
