Collider limits on new physics within micrOMEGAs[formula omitted]4.3

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 summaryProgram title: micrOMEGAs4.3Program Files doi:http://dx.doi.org/10.17632/4ck6jf5vxf.1Licensing provisions: GNU General Public License 3 (GPL)Programming language: C and FortranJournal reference of previous version: Comput. Phys. Comm. 192 (2015) 322.Does the new version supersede the previous version?: YesReasons for the new version: The ATLAS and CMS Collaborations at the LHC have performed precision measurements of the Higgs boson as well as numerous searches for new particles. These results impose strong constraints on models of new physics and in particular of dark matter which are complementary to astrophysical and cosmological constraints.Summary of revisions: This version includes interfaces to codes that fit the Higgs signal strengths, Lilith and HiggsSignals, as well as to HiggsBounds a code that is used to derive limits from searches of new scalar particles and to SModelS that exploits the simplified models results in channels with missing energy. Specific routines to reinterpret the constraints on a new Z’ boson as well as those from monojet searches are added. A routine to automatically extract any vertex from the model file is used to automatically compute the loop-induced di-photon and di-gluon Higgs widths.Nature of problem: Dark matter models can be severely constrained by precision measurements and searches for new particles at the LHC. Dedicated tools that reinterpret recent LHC results allow for a fast and efficient probe of the parameter space of various dark matter models have been developed. Interfaces to these tools are incorporated in this new version.Solution method: To use the constraints from the LHC on the Higgs sector and on new particles, mcrOMEGAs is interfaced to the external codes Lilith, HiggsSignal, HiggsBounds and SModelS. A few dedicated modules are also provided. With these new features, micrOMEGAs_4.3 provides a generic framework for evaluating dark matter observables together with collider and non-collider constraints.
