Supernova bounds on the dark photon using its electromagnetic decay

Supernova bounds on the dark photon using its electromagnetic decay

The hypothetical massive dark photon (γ′) which has kinetic mixing with the SM photon can decay electromagnetically to e+e− pairs if its mass m exceeds 2me, and otherwise into three SM photons. These decays yield cosmological and supernovae associated signatures. We briefly discuss these signatures,...
