Abstract
The first directional dark matter search with three-dimensional tracking with head-tail sensitivity (3d-vector tracking method) was performed with the NEWAGE-0.3b' detector. The search was carried out from July 2013 to August 2017 (Run14 to Run18) at the Kamioka underground laboratory. The total live time was 434.85 days corresponding to an exposure of 4.51 kg$\cdot$days. A 90 % spin-dependent WIMP-proton cross section limit of 421 pb for 150 GeV/$c^2$ WIMPs was obtained. This is the first experimental dark matter limit obtained by a 3d-vector tracking method.
