AMIDAS: A Model-Independent Data Analysis System for Direct Dark Matter Detection Experiments — •Chung-Lin Shan — School of Physics and Astronomy, Seoul National University, San 56-1, Shillim-dong, Gwanak-gu, Seoul 151-747, Republic of Korea

Weakly Interacting Massive Particles (WIMPs) are one of the leading candidates for Dark Matter. For understanding the nature of WIMPs and identifying them among new particles produced at colliders (hopefully in the near future), determinations of their mass and their couplings on nucleons from direct detection experiments by their elastic scattering on target nuclei are essential. After our long term work on development of new model-independent data analysis methods for determining the mass and the couplings of WIMPs by using experimental data (i.e., measured recoil energies) directly, we started to combine all our simulation programs to a compact system: AMIDAS (A Model-independent Data Analysis System). The functions of AMIDAS have also been extended from pure simulations (i.e., events generating and then data analyzing) to be able to analyze (real) data either generated by some other event generating programs separately or measured in direct Dark Matter detection experiments (also hopefully in the near future). I will discuss the basic working principle of AMIDAS. The preliminary functions and some projected improvements will also be described.
