How Precisely Could We Identify WIMPs Model-Independently with Direct Dark Matter Detection Experiments

In this talk we present data analysis methods for reconstructing the mass and couplings of Weakly Interacting Massive Particles (WIMPs) by using directly future experimental data (i.e., measured recoil energies) from direct Dark Matter detection. These methods are independent of the model of Galactic halo as well as of WIMPs. The basic ideas of these methods and the feasibility and uncertainties of applying them to direct detection experiments with the next generation detectors will be discussed.Comment: 14 pages, 8 figures, typos fixed, one conclusion modified, to appear in the proceedings of the Seventh International Heidelberg Conference on Dark Matter in Astro and Particle Physics (Dark 2009), Christchurch, New Zealand, 19-23 January, 200
