micrOMEGAs3.1: a program for calculating dark matter observables
Résumé
micrOMEGAs is a code to compute dark matter observables in generic extensions
of the standard model. This new version of micrOMEGAs is a major update which
includes a generalization of the Boltzmann equations to accommodate models with
asymmetric dark matter or with semi-annihilation and a first approach to a
generalization of the thermodynamics of the Universe in the relic density
computation. Furthermore a switch to include virtual vector bosons in the final
states in the annihilation cross sections or relic density computations is
added. Effective operators to describe loop-induced couplings of Higgses to
two-photons or two-gluons are introduced and reduced couplings of the Higgs are
provided allowing for a direct comparison with recent LHC results. A module
that computes the signature of DM captured in celestial bodies in neutrino
telescopes is also provided. Moreover the direct detection module has been
improved as concerns the implementation of the strange "content" of the
nucleon. New extensions of the standard model are included in the distribution.
