Dark matter direct detection rate in a generic model with micrOMEGAs_2.2
چکیده انگلیسی

We present a new module of the micrOMEGAs package for the calculation of WIMP–nuclei elastic scattering cross sections relevant for the direct detection of dark matter through its interaction with nuclei in a large detector. With this new module, the computation of the direct detection rate is performed automatically for a generic model of new physics which contains a WIMP candidate. This model needs to be implemented within micrOMEGAs 2.2.Program summaryProgram title: micrOMEGAs2.2Catalogue identifier: ADQR_v2_2Program summary URL:http://cpc.cs.qub.ac.uk/summaries/ADQR_v2_2.htmlProgram obtainable from: CPC Program Library, Queen's University, Belfast, N.

Phys. Comm. 177 (2007) 894Does the new version supersede the previous version?: YesNature of problem: Calculation of the relic density and of direct and indirect detection rates of the lightest stable particle in a generic new model of particle physics.Solution method: In numerically solving the evolution equation for the density of darkmatter, relativistic formulae for the thermal average are used. All tree-level processes for annihilation and coannihilation of new particles in the model are included. The cross-sections for all processes are calculated exactly with CalcHEP after definition of a model file. Higher-order QCD corrections to Higgs couplings to quark pairs are included. The coefficients of the effective Lagrangian which describes the interaction of WIMPS with nucleons are extracted automatically.Reasons for new version: This version contains a new module for the computation of the rate for the direct detection of dark matter through its interaction with nuclei in a large detector.Summary of revisions:
• New module for the calculation of the WIMP–nuclei elastic scattering cross sections relevant for the direct detection of dark matter through its interaction with nuclei in a large detector. The computation of the direct detection rate is performed automatically for a generic model of new physics which contains a WIMP candidate.
• Different nuclear form factors or WIMPs velocity distribution can easily be implemented by the user.
• Implementation of non-supersymmetric models such as a little Higgs model and a model with a right-handed neutrino dark matter.Unusual features: Depending on the parameters of the model, the program generates additional new code, compiles it and loads it dynamically.Running time: 0.2 sec
