NEWAGE PROJECT — DARK MATTER DETECTION WITH AN ADVANCED GASEOUS TRACKING DEVICE

Measuring the distribution of nuclear recoil angles is said to be one of the most reliable methods to identify a positive sign of weakly interacting massive particles (WIMPS) which are leading candidates for the cold dark matter. We evaluated the detection feasibility with CF4 gas for spill-dependent (SD) interactions and Xe gas for spin-independent (SI) interactions taking into account the performance of the p-TPC which is an existing three-dimensional tracking detector. We consequently found that the p-TPC filled with CF4 gas can reach the best sensitivity of the current experiments for SD interactions with even a 0.3 m3 . year of exposure at Kamioka Observatory (2700 m.w.e.). We also found it is possible to explore the theory regions predicted by minimal supersymmetric extensions of the standard model (MSSM) via SD and SI interactions with a sufficient exposure (300 m3 . year).
