Proposal to Search for a Dark Photon in Positron on Target Collisions at DAΦNE Linac
Keyword(s):
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 present paper proposes a search for such particles in thee+e-→Uγprocess in a positron-on-target experiment, exploiting the positron beam of the DAΦNE linac at the Laboratori Nazionali di Frascati, INFN. In one year of running a sensitivity in the relative interaction strength down to ~10−6is achievable, in the mass region from 2.5 MeV<MU<20 MeV. The proposed experimental setup and the analysis technique are discussed.
