The PADME experiment at LNF

Understand

Massive photon-like particles are predicted in many extensions of the Standard Model.

• They have interactions similar to the photon, are vector bosons, and can be produced together with photons.
• The PADME experiment proposes a search for the dark photon ($A'$) in the $e^+e^- \to \gamma A'$ process in a positron-on-target experiment, exploiting the positron beam of the DA$\Phi$NE linac at the Laboratori Nazionali di Frascati, INFN.
• In one year of running a sensitivity in the relative interaction strength down to $10^{-6}$ is achievable, in the mass region from 2.5 MeV $<M_{A'}<$ 22.5 MeV.
