Search for Leptonic Decays of Dark Photons at NA62
Original language description
The NA62 experiment at CERN, configured in beam-dump mode, has searched for dark photon decays in flight to electron-positron pairs using a sample of 1.4 x 10(17) protons on dump collected in 2021. No evidence for a dark photon signal is observed. The combined result for dark photon searches in lepton-antilepton final states is presented and a region of the parameter space is excluded at 90% confidence level, improving on previous experimental limits for dark photon mass values between 50 and 600 MeV/c(2) and coupling values in the range 10(-6) to 4 x 10(-5). An interpretation of the e(+)e(-) search result in terms of the emission and decay of an axionlike particle is also presented.
