|" Search for cold dark matter by measuring X and gamma rays. "|
We report briefly possible searches for cold dark matter (WIMPs) by measuring Xrays associated with nuclear recoils from WIMPs and gamma rays associated with inelastic scattering of WIMPs. The unique feature of the X and gamma studies is their discrete line shape of the spectrum and the un-quenched signal.
Coincident measurements of the X and gamma rays with the nuclear recoil make itpossible to clean up the WIMP signals.
