Direct versus indirect detection in mSUGRA with self-consistent halo models
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.Comment: 26 pages, 9 figure
Les Houches 2011: Physics at TeV Colliders New Physics Working Group Report
We present the activities of the "New Physics" working group for the "Physics
at TeV Colliders" workshop (Les Houches, France, 30 May-17 June, 2011). Our
report includes new agreements on formats for interfaces between computational
tools, new tool developments, important signatures for searches at the LHC,
recommendations for presentation of LHC search results, as well as additional
phenomenological studies.Comment: 243 pages, report of the Les Houches 2011 New Physics Group; fix

DarkSUSY: Computing Supersymmetric Dark Matter Properties Numerically
The question of the nature of the dark matter in the Universe remains one of
the most outstanding unsolved problems in basic science. One of the best
motivated particle physics candidates is the lightest supersymmetric particle,
assumed to be the lightest neutralino - a linear combination of the
supersymmetric partners of the photon, the Z boson and neutral scalar Higgs
particles. Here we describe DarkSUSY, a publicly-available advanced numerical
package for neutralino dark matter calculations. In DarkSUSY one can compute
the neutralino density in the Universe today using precision methods which
include resonances, pair production thresholds and coannihilations. Masses and
mixings of supersymmetric particles can be computed within DarkSUSY or with the
help of external programs such as FeynHiggs, ISASUGRA and SUSPECT. Accelerator
bounds can be checked to identify viable dark matter candidates. DarkSUSY also
computes a large variety of astrophysical signals from neutralino dark matter,
such as direct detection in low-background counting experiments and indirect
detection through antiprotons, antideuterons, gamma-rays and positrons from the
Galactic halo or high-energy neutrinos from the center of the Earth or of the
Sun. Here we describe the physics behind the package. A detailed manual will be
provided with the computer package.Comment: 35 pages, no figure
