Description
The energy threshold of traditional liquid xenon time projection chambers limits our sensitivity in detecting boron-8 neutrinos, light dark matter, and other low-energy signals. Ionization signals have demonstrated significant potential for expanding low-energy detection, but low-energy backgrounds remain the principal barriers to improving sensitivity. In this talk, we present our detailed investigations into the sources of low-energy backgrounds using PandaX-4T data and multiple methods we have developed to evaluate them.
