Constraining Dark Matter Models with a Light Mediator at the PandaX-II Experiment
Constraining Dark Matter Models with a Light Mediator at the PandaX-II Experiment
We search for nuclear recoil signals of dark matter models with a light mediator in PandaX-II, a direct detection experiment in the China Jinping underground laboratory. Using data collected in 2016 and 2017 runs, corresponding to a total exposure of 54 ton day, we set upper limits on the zero-momentum …
