Search for a heavy dark photon at future e + e − colliders
Abstract A coupling of a dark photon A ′ from a U(1) A ′ with the standard model (SM) particles can be generated through kinetic mixing represented by a parameter ϵ. A non-zero ϵ also induces a mixing between A ′ and Z if dark photon mass m A ′ is not zero. This mixing can be large when m A ′ is clo...
