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 such particles in the e +e- → gU process in a positron-on-target
experiment, exploiting the positron beam of the DAFNE 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 U < 20 MeV. The proposed experimental setup and the analysis
technique is discussed.
