Title: Higgs Portal to Dark QED

Abstract

We introduce a light dark photon $$A_\mu^\prime$$ 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-$$A^\prime$$ channel," or into multiple collimated leptons via "darkonium," depending on the mixing parameter of the $$A_\mu^\prime$$ 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.
