Abstract: Recently, a new force mediated by "Dark" photons has been the subject of intense interest in high energy physics, both theoretical and experimental, leading to a resurgence in their experimental search, with several fixed target experiments operating in the near future. On the other hand, complementary dark photon signals at colliders are model-dependent, requiring theoretical input to determine the most interesting signals. In this talk, I will describe a class of theories where the mechanism in which the dark photon mixes with the photon predicts a new particle accessible at the LHC. After describing the theory, I will discuss our analyses on simulated experimental data, which suggest substantial improvements on existing collider searches for dark photons that decay to electrons.
