NEWAGE: Direction-Sensitive Dark Matter Search

Abstract

By the recent astronomical and astrophysical observations, one fourth of the total energy of the universe was known to be in a form of the unknown particle, “dark matter”. Many experimental activities are on-going all over the world to reveal the nature of this mysterious particle. Direct detection experiments aim to detect the energy deposited to the detector on the earth by the elastic scattering of the dark matter and the ordinary matter. Among many direct detection experiments, the direction-sensitive method is said to provide a strong evidence of the dark matter due to the motion of the solar system in the galaxy. NEWAGE is one of the direction-sensitive dark matter search experiments and recently updated the world-best direction sensitive dark matter limits by the measurement in Kamioka underground laboratory.
