Dark matter, the CMSSM and lattice QCD

TL;DR

This paper uses recent lattice QCD results to refine dark matter detection predictions within the CMSSM, revealing significantly smaller cross sections and impacting search strategies.

Contribution

It introduces updated dark matter cross section estimates in the CMSSM using new lattice QCD data, improving previous predictions.

Findings

Predicted cross sections are at least ten times smaller than earlier estimates.

Results have important implications for dark matter detection experiments.

Enhanced accuracy in dark matter predictions within the CMSSM.

Abstract

Recent lattice measurements have given accurate estimates of the light and strange quark condensates in the proton. We use these new results to significantly improve the dark matter predictions in a set of benchmark models that represent different scenarios in the constrained minimal supersymmetric standard model (CMSSM). Because the predicted cross sections are at least an order of magnitude smaller than previously suggested, our results have significant consequences for dark matter searches.
