Dark matter signals in deflected mirage mediation

TL;DR

This paper explores the parameter space of deflected mirage mediation models, analyzing neutralino properties and detection prospects, finding compatibility with current cosmological and experimental constraints and predicting future detectability.

Contribution

It provides a detailed analysis of neutralino dark matter signals within DMM models, highlighting regions consistent with cosmological and experimental bounds and forecasting future detection potential.

Findings

Certain DMM parameter regions align with WMAP constraints.

Current Xenon10 bounds do not exclude the model space.

Future xenon experiments will probe significant parts of the parameter space.

Abstract

We investigate the parameter space of a specific class of model within the deflected mirage mediation (DMM) scenario. We look at neutralino properties and compute the thermal relic density as well as interaction rates with xenon direct detection experiments. We find that there are portions of the parameter space which are in line with the current WMAP constraints. Further we find that none of the investigated parameter space is in conflict with current bounds from the Xenon10 experiment and that future large-scale liquid xenon experiments will probe a large portion of the model space.
