Global fits of simplified models for dark matter with GAMBIT

Abstract Simplified models provide a useful way to study the impacts of small number new particles on experimental observables and interplay those observables, without need construct an underlying theory. In this study, we perform global fits simplified dark matter with using up-to-date set likelihoods for indirect detection, direct detection collider searches. We investigate in which scalar or fermionic candidate couples quarks via s -channel vector mediator. Large parts parameter space survive each model. case Dirac Majorana fermion matter, excesses LHC monojet searches relic density limits tend prefer resonance region, where has approximately half mass A combination axial-vector couplings also leads competing constraints from unitarity violation.
