We consider the prospects to use polarized dark -matter detectors to discriminate between various dark -matter models . If WIMPs are fermions and participate in parity -violating interactions with ordinary matter , then the recoil -direction and recoil -energy distributions of nuclei in detectors will depend on the orientation of the initial nuclear spin with respect to the velocity of the detector through the Galactic halo . If , however , WIMPS are scalars , the only possible polarization -dependent interactions are extremely velocity -suppressed and , therefore , unobservable . Since the amplitude of this polarization modulation is fixed by the detector
speed through the halo , in units of the speed of light , exposures several times larger than those of current experiments will be required to be probe this effect . |
