| dc.description | The light dark matter model can explain both the primordial abundance of dark matter and the anomalous 511 keV gamma-ray signal from the galactic center. This model posits a light neutral scalar, χ, with a mass in the range 1 MeV < Mchi < 10 MeV, as well as a light neutral spin-1 boson, U, which mediates the annihilation channel χχ-> e+e-. Since the dark matter particle is light, its number density is relatively large if it accounts for a local dark matter density of 0.3 GeV/cm^3. We consider an experiment in which a low-energy, high-current electron beam is passed through a long evacuated tube, and elastic scattering of electrons off dark matter particles is observed. The kinematics of this process allow a clean separation of the signal process from scattering off residual gas in the tube, and also a direct measurement of Mchi. | |
