Cornell Dark Photon Search

ORAL

Abstract

We report on the concept and preliminary design of a search for dark photons. The A$'$ gauge boson of a nonstandard U(1) gauge symmetry (dark photon) may be produced in association with a normal photon in e+e- annihilation via $e^+e^-\to \gamma A'$. In the proposed experiment, the 5 GeV $e^+$ beam produced in Cornell's synchrotron is incident on a fixed target; following detection of the real photon, the A$'$ is reconstructed as a missing mass. This search strategy is wholly independent of the A$'$ decay channels. The sensitivity in A$'$ mass and kinetic coupling constant will be discussed.
