A directional signal is expected to provide clear evidence of direct dark
matter detection. In addition to the characteristic anisotropy signal,
directional detection can potentially extend the search below the so-called neutrino-floor where neutrino-nucleus coherent scatterings make serious background.
This method is useful for the low mass WIMPs search with particle identification.

We are going to discuss the physics reach and the experimental challenges of directional WIMP-like Dark Matter searches, illustrating the concept of the CYGNUS-TPC international collaboration and how the CYGNO (a CYGNus TPC module with Optical readout) effort fits into it. The most innovative CYGNO's features are the exploitation of sCMOS cameras and PMTs, to optically readout the GEMs...

A variety of experiments have been developed over the past decades, aiming to detect Weakly Interactive Massive Particles (WIMPs) via their scattering in a detector medium. The sensitivity of these experiments has improved with a tremendous speed due to a constant development of the detectors and analysis methods. Detectors that are able to reconstruct the direction of the nucleus recoiling...

NEWAGE is a directional dark matter search experiment using a micro-TPC. We marked the best direction-sensitive limit in 2015. Meanwhile, the substrate of μ-PIC was found to be the dominant background source.
We developed a new readout device, namely a low alpha-ray emitting μ-PIC (LAμ-PIC). The U/Th contamination of the LA μ-PIC was found to be 100 times less than that of the conventional...

Today, the situation in direct dark matter (DM) detection is controversial: The DAMA/LIBRA experiment observes an annual modulation signal at high confidence which is perfectly compatible with a galactic halo of DM particles which interact in their NaI target crystals. However, in the standard scenario on DM halo and DM interaction properties, the DAMA signal contradicts numerous other...

SABRE is a dark matter direct detection experiment, based on NaI (Tl) scintillating crystals as target material. A primary goal of the experiment is to test the dark matter interpretation of the DAMA/LIBRA annual modulation signal. To reach its purpose, SABRE features arrays of ultra-low background NaI (Tl) crystals immersed in a liquid scintillator active veto system and twin experiments, one...
