Abstract(summary):

The Heavy Photon Search (HPS) experiment in Hall-B at Jefferson Lab will search for new heavy vector boson(s), aka "heavy photons", in the mass range of 20 MeV/c(2) to 1000 MeV/c(2) using the scattering of high energy, high intensity electron beams off a high Z target. The proposed measurements will cover the region of parameter space favored by the mum g-2 anomaly, and will explore a significant region of parameter space, not only at large couplings (alpha'/alpha > 10(-7)), but also in the regions of small couplings, down to alpha'/alpha similar to 10(-10). The excellent vertexing capability of the Si-tracker uniquely enables HPS to cover the small coupling region. Also, HPS will search for heavy photons in an alternative to the e(+)e(-) decay mode, in the heavy photon's decay to mu(+) mu(-).
