Abstract

Abstract We report the results of a search for dark photon in-flight decays to μ ⁺ μ ⁻ pairs at NA62. Dark photons could be produced by dumping protons onto a copper-iron absorber, reach the NA62 decay volume more than 80 m downstream of the dump and decay therein. The measurement is based on data collected in 2021 which correspond to 1.4 × 10¹⁷ dumped protons.
