Modeling Dark Photon Oscillations in Our Inhomogeneous Universe

14 Apr 2020Andrea CaputoHongwan LiuSiddharth Mishra-SharmaJoshua T. Ruderman

A dark photon may kinetically mix with the Standard Model photon, leading to observable cosmological signatures. The mixing is resonantly enhanced when the dark photon mass matches the primordial plasma frequency, which depends sensitively on the underlying spatial distribution of electrons... (read more)
