Enhanced long-lived dark photon signals at the LHC

Van Que Tran

The LHC searches for long-lived dark photons with GeV scale mass in the kinetic mixing models suffer from the fact that the same coupling that makes the dark photon long-lived suppresses the production rate. In this talk, I will present a model where the long-lived dark photon signals at the LHC can be enhanced. The long-lived dark photons in the model can be discriminated from the background by measuring the time delay signal in the precision timing detectors which are proposed to be installed in the LHC upgrades. Searches with current and future LHCb data are also discussed.
