[Hps] Abstract for Photon 2013

[Maurik Holtrop]

Dear HPS Collaborators,

In a bit of a hurry, I will soon submit the following abstract to the Photon 2013 conference. Your comments would be greatly appreciated.

Thanks,
	Maurik

-----------------------------------
In recent years much interest has been given to new physics models which have hidden sectors with extra massive U(1) gauge bosons, so-called heavy photons (or dark photons). Such theories could explain the dark matter problem and various anomalies in astrophysical observations. The Heavy Photon Search Experiment (HPS) at Jefferson Lab is a new experiment designed to look for these heavy photons in the mass range 20-1000 MeV that couple to electrons through kinematic mixing with couplings $\alpha'/\alpha$ in the range 10$^{-5}$ to 10$^{-10}$. The HPS will search for the $e^+e^-$ or $\mu^+\mu^-$ decay of the heavy photon, possibly with a detached vertex, using a compact forward spectrometer, which employs silicon microstrip detectors for vertexing and tracking, and a PbWO4 electromagnetic calorimeter for fast triggering. The design, performance, and results from the test run apparatus will be discussed, along with the collaboration’s plans for future construction and data taking.
