Revisiting simplified dark matter models in terms of AMS02 and FermiLAT
Abstract
We perform an analysis of the simplified dark matter models in the light of cosmic ray observables by AMS02 and FermiLAT. We assume fermion, scalar or vector dark matter particle with a leptophobic spin0 mediator that couples only to Standard Model quarks and dark matter via scalar and/or pseudoscalar bilinear. The propagation and injection parameters of cosmic rays are determined by the observed fluxes of nuclei from AMS02. We find that the AMS02 observations are consistent with the dark matter framework within the uncertainties. The AMS02 antiproton data prefer 30 (50) GeV  5 TeV dark matter mass and require an effective annihilation cross section in the region of 4 × 10^{27} (7 × 10^{27})  4 × 10^{24} cm^{3}/s for the simplified fermion (scalar and vector) dark matter models. The cross sections below 2 × 10^{26} cm^{3}/s can evade the constraint from FermiLAT dwarf galaxies for about 100 GeV dark matter mass.
