Description
We consider a QCD-like theory with two light flavours, in which the DM candidate is a dark neutron. In this scenario, a non-vanishing theta angle triggers velocity-dependent self-interactions with dark pions acting as light mediators. By further considering a dark photon portal to the SM, direct-detection experiments probe CP violation via magnetic- and electric- dipole-mediated scatterings induced by the theta angle. We further discuss indirect detection signatures from DM annihilation, which are p-wave or loop suppressed, as well as thermalization in the early Universe and the resulting relic abundance.
