Much compelling evidence from astroparticle physics and cosmology indicate that the major matter component in the Universe is dark matter, accounting for about 85% with the remaining 15% ordinary matter. Nevertheless, people still know little about dark matter, including its mass and other properties. Many models predict dark matter particles could couple with ordinary particles at the weak interaction level, so it is possible to capture the signal of dark matter particles with direct detection experiment.
