Summary
Recently, the idea of the existence of a hidden sector of particles, connected with the SM
only through a vector mediator - dark photon - was revived. The PADME experiment aims
to search for dark photon, A’, in positron-on-target annihilation (e+e− ->A') exploiting
the 550 MeV positron beam from the DAFNE Linac. The reconstruction of the missing
mass through the detection of the recoil photon allows to probe invisible A’ final states.
The experiment aims to collect 10^13 positrons on target by the end of 2018, allowing
to probe for dark photon with mass up to 24MeV and a relative coupling down to
epsilon 10^−3. PADME was formally approved by the INFN at the end of 2015 and is in its
construction phase.
