Search for Light Dark Matter–Electron Scattering in the PandaX-II Experiment

We report constraints on light dark matter through its interactions with shell electrons in the PandaX-II liquid xenon detector with a total 46.9 tonnes / day exposure. To effectively search for these very low energy electron recoils, ionization-only signals are selected from the data. 1821 candidat...
