Advancements in Dark Matter Research: From Ionization Signals to Neutrino Detectors

The PandaX experiment, located at the China Jinping Underground Laboratory, has set new constraints on the search for light dark matter using ionization signals. By focusing on the ionization signal (S2) in dual-phase xenon detectors, the researchers were able to reduce the energy threshold and derive constraints for light dark matter particles. Although no significant excess was observed, the constraints delineate a mass range for various types of dark matter interactions. These findings provide the most stringent constraints yet and could inform future searches for light dark matter using dual-phase xenon detectors. The PandaX experiment continues to collect data and improve its sensitivity in the search for dark matter.
