Monochromatic single photon events at the muon collider
The cross section for lepton pair annihilation into a photon and a dark photon or an axionlike particle is constant for large center-of-mass energies because some of the portal operators coupling the Standard Model and dark sector are proportional to the energy. Feebly coupled though they are, these...
