title = "Higgs portal to dark QED",
abstract = "We introduce a light dark photon Aμ′ to the minimal Higgs portal model, by coupling the Higgs boson to {"}dark QED{"}containing fermionic dark matter, which gives rise to rich and interesting collider phenomenology. There are two prominent features in such a simple extension - the Higgs boson could have decays into the long-lived dark photon through the {"}mono-A′ channel,{"}or into multiple collimated leptons via {"}darkonium,{"}depending on the mixing parameter of the Aμ′ with the visible photon. We initiate a study on the possibility of probing the parameter space of the model in both the energy and the lifetime frontiers at the Large Hadron Collider.",
