Phenomenological analysis of multi-pseudoscalar mediated dark matter models

A bstract Non-minimal simplified extensions of the Standard Model have gained considerable currency in context dark matter searches at LHC, since they predict enhanced mono-Higgs and mono- W/Z signatures over large parts parameter space. However, these non-minimal models obviously lack simplicity directness original models, are more heavily dependent on model assumptions. We propose to classify generically basis additional mediator(s) particles. As an example, we take up a scenario involving multiple pseudoscalar mediators, single Dirac particle, latter being popular introduction ensure ultraviolet completion theories with fields. In chosen scenario, discuss viable channels relevance future runs LHC. These then compared minimal scenarios distinguishing features pinpointed.
