Searching for dark photons at the LHeC and FCC-he

Extensions of the Standard Model (SM) gauge group with a new U ( 1 ) X predict an additional gauge boson. Through kinetic mixing with the SM photons featured by a coupling ε , the ensuing so-called dark photons γ ′ , which acquire mass as a result of the breaking of the gauge group U ( 1 ) X , can i...
