Abstract
Abstract
PADME (Positron Annihilation into Dark Matter Experiment) is a fixed target experiment located at the Beam Test Facility (BTF) at the Laboratori Nazionali di Frascati (LNF) designed to search for a massive dark photon

/c2 can be achieved by collecting 4 × 1013 positrons on target. Run 2 data taking finished in December 2020 and allowed to reach an integrated luminosity of 5 × 1012 positrons on target.
