Scrutinizing a massless dark photon: Basis independence
A new U(1)X gauge boson field X can have renormalizable kinetic mixing with the standard model (SM) U(1)Y gauge boson field Y. This mixing induces interactions of X with SM particles even though X starts as a dark photon without such interactions. If the U(1)X is not broken, both the dark photon fie...
