Abstract

Results from the LHC put severe constraints on models of new physics. This includes constraints on the Higgs sector from the precise measurement of the mass and couplings of the 125 GeV Higgs boson, as well as limits from searches for other new particles. We present the procedure to use these constraints in micrOMEGAs by interfacing it to the external codes Lilith, HiggsSignals, HiggsBounds and SModelS. A few dedicated modules are also provided. With these new features, micrOMEGAs_4.3.4 provides a generic framework for evaluating dark matter observables together with collider and non-collider constraints. Program summary Program title: micrOMEGAs4.3 Program Files doi: http://dx.doi.org/10.17632/4ck6jf5vxf.1 Licensing provisions: GNU General Public License 3 (GPL) Programming language: C and Fortran Journal reference of previous version: Comput.
