We perform a detailed analysis of the detection prospects of neutralino dark matter in the mSUGRA framework. We focus on models with a thermal relic density, estimated with high accuracy using the DarkSUSY package, in the range favored by current precision cosmological measurements. Direct and indirect detection rates are computed implementing two models for the dark matter halo, tracing opposite regimes for the phase of baryon infall, with fully consistent density profiles and velocity distribution functions. This has allowed, for the first time, a fully consistent comparison between direct and indirect detection prospects. We discuss all relevant regimes in the mSUGRA parameter space, underlining relevant effects, and providing the basis for extending the discussion to alternative frameworks. In general, we find that direct detection and searches for antideuterons in the cosmic rays seems to be the most promising ways to search for neutralinos in these scenarios.

We also include in our survey one model in which the dark matter profile is not defined by equation ([ref]), but by the relation [equation] where \(r_0\) and $ρ_0$ are fiducial distance and density parameters, respecively (for our galaxy, \(r_0≈11.7\) kpc and $ρ_0≈0.34 GeV cm^-3$ [ref] ).
