Abstract
There are presently several discrepancies in decays of mesons suggesting new physics coupling to quarks and leptons. We show that a , with couplings to quarks and muons that can explain the -decay anomalies, can also couple to dark matter in a way that is consistent with its relic abundance, direct detection limits, and hints of indirect detection. The latter include possible excess events in antiproton spectra recently observed by the AMS-02 experiment. We present two models, having a heavy (light) with and fermionic dark matter with mass , producing excess antiprotons with energies of . The first model is also compatible with fits for the Galactic center GeV gamma-ray excess.
