<br>
The Dark Forces explanation of dark matter predicts a low mass (0.01-10
GeV/c<sup class="moz-txt-sup">2</sup>)
scalar or vector boson that kinetically mixes with the photon.
DarkLight will look for evidence of the dark force by search for an
electron positron resonance in ep->epee scattering. The experiment
makes use of the 1MW free electron laser beam, a dense H2 target and a
detector able to measure all three final state leptons and the
recoiling proton, allowing full reconstruction of each event.
<br>
<br>
After briefly reviewing the theory, I will describe our experiment
and several other experiments exploring other parts of the parameter
space.
