Comparison of Different Detection Paradigm for WMIPs

Abstract

Based on astrophysics observation, dark matter accounts for approximately 84% of all matter in the universe, with the remaining 16% being ordinary matter. According to the prevailing scientific model, dark matter particles are supersymmetric particles with a mass of 100 GeV (about the mass of 100 protons) with the density about 5000 particles m^-3. Yet such a dominant substance dominates the universe, but one has not detected yet. Among various candidate, WIMPs are one of the most appealing one that plenty of facilities aim to detect. In this essay, the detection principles and some recent results of two representatives of the state-of-art mainstream detection methods were presented, i.e., the ‘Wukong’ astronomical satellite (DAMPE) and the Jinping Mountains of Sichuan Province, China (CJPL). It was shown that ‘Wukong’ has successfully detected an electron-positron pairs at an energy of 0.9 Tev. In Jinping, experiments are proposed to detect liquid argon dark matter. In this review, the two methods of detecting dark matter will be compared and the advantages, disadvantages will be analyzed. These results shed light on guiding further exploration of dark matter.
