Dark sector production via proton bremsstrahlung

Experiments using proton beams at high luminosity colliders and fixed target facilities provide impressive sensitivity to new light weakly coupled degrees of freedom. With these experiments in mind, we revisit the production dark vectors scalars via bremsstrahlung, making use a model that describes underlying nucleon scattering cross-section forward direction due pomeron exchange. We compare resulting distributions rates with those obtained variants Fermi-Weizsacker-Williams approximation, rate for range beam energies, including relevant proposed Forward Physics Facility High Luminosity-LHC.
