Abstract:Dark photons are predicted by various new physics models, and are being intensively studied in a variety of experiments. In the first part of this paper, we obtain partial wave unitarity constraints on the dark photon parameter space from the allowed V V → V V scattering processes in the limit of large center-of-mass energy, where V = W, Z. In the second part of the paper, searches are performed using the expected differential rates with a realistic detector simulation including a comprehensive set of backgrou… Show more
