Query: Simplified dark matter models in the light of AMS-02 antiproton data   In this work we perform an analysis of the recent AMS-02 antiproton flux and
the antiproton-to-proton ratio in the framework of simplified dark matter
models. To predict the AMS-02 observables we adopt the propagation and
injection parameters determined by the observed fluxes of nuclei. We assume
that the dark matter particle is a Dirac fermionic dark matter, with
leptophobic pseudoscalar or axialvector mediator that couples only to Standard
Model quarks and dark matter particles. We find that the AMS-02 observations
are consistent with the dark matter hypothesis within the uncertainties. The
antiproton data prefer a dark matter (mediator) mass in the 700 GeV--5 TeV
region for the annihilation with pseudoscalar mediator and greater than 700 GeV
(200 GeV--1 TeV) for the annihilation with axialvector mediator, respectively,
at about 68% confidence level. The AMS-02 data require an effective dark matter
annihilation cross section in the region of 1x10^{-25} -- 1x10^{-24}
(1x10^{-25} -- 4x10^{-24}) cm^3/s for the simplified model with pseudoscalar
(axialvector) mediator. The constraints from the LHC and Fermi-LAT are also
discussed.
