The PADME experiment at Laboratori Nazionali di Frascati
  The PADME experiment will search for the invisible decay of Dark Photons produced in interactions of positron from the DA$\Phi$NE Linac on a target. The collaboration aims at reaching a sensitivity of $\sim10^{-3}$ on the coupling constant for values of Dark Photon masses up to $23.7\,\mbox{MeV}$.
