摘要: Weakly Interacting Massive Particles (WIMPs) are one of the leading candidates for Dark Matter. Currently, most promising method to detect WIMPs is direct detection recoil energy deposited in a low-background laboratory detector due elastic WIMP-nucleus scattering. So far usual procedure has been predict event rate based on some model(s) Galactic halo from cosmology and elementary particle physics. The aim this work invert process. In thesis I present methods which allow reconstruct (the moments of) WIMP velocity distribution function as well determine mass spectrum experimental data directly. reconstruction further extended take into account annual modulation rate. Moreover, amplitude an alternative, better way confirming have discussed. On other hand, determination by combining two (or more) experiments with different materials developed. All formulae expressions given here not only independent model but also that WIMPs. This means we need neither yet unknown density near Earth nor cross section. information measured energies their measuring times.
