Interest in new physics models including so-called hidden sectors has increased in recent years as a result of anomalies from astrophysical observations. The Heavy Photon Search (HPS) experiment proposed at Jefferson Lab will look for a mediator of a new force, a GeV-scale massive U(1) vector boson, the Heavy Photon, which acquires a weak coupling to electrically charged matter through kinetic mixing. The HPS detector, a large acceptance forward spectrometer based on a dipole magnet, consists of a silicon tracker-vertexer, a lead-tungstate electromagnetic calorimeter, and a muon detector. HPS will search for the e+e- or mu+mu- decay of the Heavy Photon produced in the interaction of high energy electrons with a high Z target, possibly with a displaced decay vertex. In this article, the description of the detector and its sensitivity are presented.
