Implication of the dark axion portal for the EDM of fermions and dark matter probing with NA64e, NA64μ, LDMX, M3, and B a B ar

The link between ordinary Standard Model (SM) photons and both dark photons and axion-like particles (ALPs) can be introduced through the dark axion portal coupling. Given the dark axion portal setup, in the present paper we refer to the dark photon as th
