Description

We reexamine the model-independent data analysis methods for extracting properties of Weakly Interacting Massive Particles (WIMPs) using data (measured recoil energies) from direct Dark Matter detection experiments directly and, as a more realistic study, consider small fractions of residue background events, which pass all discrimination criteria and then mix with other real WIMP-induced signals in data sets. In this talk, the effects on the determination of the mass of halo Dark Matter particles as well as their spin-independent couplings on nucleons will be discussed.
