Exploiting the materials signature in cryogenic WIMP detectors

The mass number dependence of the WIMP-nucleus scattering offers a method for identifying a true WIMP signal over a neutron background.

Sammanfattning:The mass number dependence of the WIMP-nucleus scattering offers a method for identifying a true WIMP signal over a neutron background. In this paper we present a study on using a combination of ZnWO4 and CaWO4 absorbers to exploit this materials signature for WIMP detection. We show that already modest exposure in the region of 5 kg years should allow the detection of WIMP interaction for cross sections smaller than current experimental sensitivities. The combination of these two tungstates could form the basis of the first multi-target detector capable of WIMP identification through materials signature.
