The Relic [Ongoing] - Version: 0.01 ##TOP##

The Heavy Photon Search Group at SLAC is collaborating with physicists at Jefferson Lab, INFN, IN2P3, UNH and UCSC in an experiment aimed at discovering a hidden-sector photon (aka "dark" photon or "heavy" photon). Such a particle could have mass in the range 0.01 to 0.5 GeV, couple weakly to electrons, and decay to e + e - . It would be produced by electron bremstrahlung on a heavy target, and be identified as a narrow e + e - resonance. Weak couplings of this heavy photon to electrons account for its not yet having been discovered and, if weak enough, can give rise to separated vertices in its decay, providing a spectacular signature. Dark photons have become very topical because ongoing searches for SUSY WIMPs have so far been unsuccessful, leading to speculation that the dark matter may be light,
