Description

Directional detection of galactic Dark Matter is a promising search strategy for discriminating genuine WIMP events from background ones. Indeed, due to the Earth rotation around the Galactic center through the dark matter halo, the WIMP-induced recoil distribution should be pointing toward the Cygnus Constellation. I will present a comprehensive statistical method allowing to recover from a realistic simulated recoil map (containing both signal and background events), the main incoming direction of the WIMP signal, thus proving its galactic origin. Hence, the goal of this new statistical method is not to reject the background hypothesis, but rather to identify a genuine WIMP signal even in the case of a large signal to noise ratio.
