Implications of XENON100 and LHC results for Dark Matter models

TL;DR

This paper analyzes recent Xenon100 and LHC data to evaluate their impact on various dark matter models, disfavoring some scenarios like Inelastic Dark Matter and the Higgs-resonance region, and highlighting shifts in preferred parameter spaces.

Contribution

It provides a comprehensive fit of recent experimental data to multiple dark matter models, revealing which scenarios are disfavored and how the preferred parameter space has shifted.

Findings

Inelastic Dark Matter is disfavored by Xenon100 data.

The scalar singlet DM model's constrained limit is disfavored.

LHC data excludes the Higgs-resonance region of DM freeze-out.

Abstract

We perform a fit to the recent Xenon100 data and study its implications for Dark Matter scenarios. We find that Inelastic Dark Matter is disfavoured as an explana- tion to the DAMA/LIBRA annual modulation signal. Concerning the scalar singlet DM model, we find that the Xenon100 data disfavors its constrained limit. We study the CMSSM as well as the low scale phenomenological MSSM taking into account latest Tevatron and LHC data (1.1/fb) about sparticles and Bs \rightarrow {\mu}{\mu}. After the EPS 2011 conference, LHC excludes the "Higgs-resonance" region of DM freeze-out and Xenon100 disfavors the "well-tempered" bino/higgsino, realized in the "focus-point" region of the CMSSM parameter space. The preferred region shifts to heavier sparticles, higher fine-tuning, higher tan {\beta} and the quality of the fit deteriorates.
