Description
I and collaborators revised model independent dark photon bound with recent observation. By assuming minimal assumption on dark photon, irreducible dark photon abundance is estimated. This irreducible abundance can provide dark photon bound with cosmological and astrophysical observation such as CMB, BBN, galactic Gamma ray. Also existence of dark photon can affect supernovae evolution so that there are bounds from it.
