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,...
