| Abstract: |
Primordial black holes (PBH) can be a good source of feebly interacting particles. The PBH undergoes the comventional Hawking radiation such as photons and charged particles, which can result in gamma-rays and can be detected by present and future gamma-ray telescope. We use the PBH to probe dark photon with a mass less than 1 MeV such that the main decay is into 3 photons. We show that the presence of dark photons can modify the gamma-ray spectrum that is distinguishable from the conventional case. We estimate the sensitivity.
