DESCRIPTION:Narbe Kalantarians\, Hampton University\n\nRecent theories of d
ark matter predict A’ gauge bosons in the mass range of 0.01-10 GeV that
\ncouple to charged fermions with a strength of α\;’/α\;
17\;Μ\;~ 10-4 of the photon or less. The DarkLight (D
etecting A Resonance Kinematically with eLectrons Incident on a Gaseous Hy
drogen Target) experiment intends to use the 1 MW 100 MeV electron beam at
the Jefferson Lab Free Electron Laser incident on a 1019 H2/cm2 thick target to study the process e- +
p -> e- + p +e- + e+. A dark force partic
le would show up as a narrow resonance in the radiated e+ - e- system. DarkLight\nwould explore the A’ mass region 10-100 Me
V with sensitivity to couplings as low as a’/aEM ~10-7
sup> with 1/ab of data.
