Light dark photon and fermionic dark radiation for the Hubble constant and the structure formation
Motivated by the tensions in the Hubble constant H0 and the structure growth σ8 between Planck results and other low redshift measurements, we discuss some cosmological effects of a dark sector model in which dark matter (DM) interacts with fermionic dark radiation (DR) through a light gauge boson (...
