【 摘 要 】

At the end of 2015, INFN formally approved a new experiment, PADME, to search for invisible decays of the A' dark photon at the DAFNE Linac in Frascati. The experiment is designed to detect the A' produced in positron-on-fixed target annihilation, by measuring the final state missing mass. The collaboration aims to complete the design and construction of the experiment by the end of 2017 and to collect ∼1013positrons on target by the end of 2018, thus reaching a sensitivity on the coupling constant of ∼103and on the dark photon mass up to ∼ 23.7 MeV/c2
