Maximum And Minimum Dark Matter Detection Cross Sections

TL;DR

This paper analyzes the range of neutralino-proton cross sections in various supergravity models, showing current detectors cover significant parameter space and future detectors could cover nearly all, except some regions with very heavy spectra.

Contribution

It provides a comprehensive examination of dark matter detection cross sections across multiple supergravity models, highlighting the potential and limitations of current and future detectors.

Findings

Current detectors sample significant SUSY parameter space.

Future detectors could sample almost all SUSY parameter space.

Some inaccessible regions have heavy squark/gluino spectra beyond 1 TeV.

Abstract

The range of neutralino-proton cross sections for R-parity preserving supergravity models with GUT scale unification of the gauge coupling constants is examined. The models considered here are mSUGRA, models with non universal soft breaking and D-brane models. It is found that the current dark matter detectors are sampling significant parts of the SUSY parameter space and future detectors could sample almost the entire space. The special regions of parameter space that may be inaccessible to future detectors are seen to have a squark/gluino spectra beyond 1 TeV, but observable at the LHC.
