Dark Photon Search with PADME at LNF

Dark Matter elusiveness could be explained by speculating that it lives in a separate sector with respect to the Standard Model and that interacts with it only by means of messengers. The simplest model foresees just one messenger: a, possibly massive, vector boson given by a new U(1) symmetry. This mediator can faintly mix with the photon and, hence, interact with SM charged particles, seeing an effective charge equal to epsilon e, with e SM charge. The PADME experiment, hosted at Laboratori Nazionali di Frascati, is designed to search for such kind of particle, looking for its production in e(+)e(-) annihilations. Exploiting the DA Phi NE linac, the collaboration aims to collect 10(13) positrons on target by the end of 2018, reaching a sensitivity of similar to 10(-3) for masses up to 23.7 MeV.
