Studying Dark Photon Models in Decays of Neutral Mesons
Decays of light pseudoscalar mesons play an important role in the search for dark matter signals in fixed-target experiments. The intermediate vector meson state is shown to be of importance in the analysis of dark photon physics in the decays of neutral mesons. Constraints on the dark photon model for the optimistic statistics of the NA64 experiment with a beam of negative pions are presented.
