SJTU PandaX-II experimental results are selected into Physics Highlights of the Year

December 22, 2017      Author: Chen Xun

On December 18, 2017, Physics, the online magazine of the American Physical Society (APS), published the highlights of 2017 in the field of international physics. "WIMPs Are No-Shows, Again" is one of eight highlights. PandaX-II experiment, the XENON1T experiment in Europe and the LUX experiment in the United States all contributed to this research highlight. The article comments: "Of the many theories about dark matter, the most popular describes it as composed of weakly interacting massive particles (WIMPs). But this "favored" theory is now looking a little, well, less favored. In the last 16 months, the collaborations behind the world's three largest dark matter detectors reported that they had observed no WIMPs in the theoretically expected mass range."(Link:

PandaX-II experiment was conducted by cooperation group (including Peking University, Shandong University, etc.) and under the leadership of Ji Xiangdong and Liu Jianglai from SJTU. PandaX-II consisted of 584 kg of liquid xenon and the experiment began operating in Jinping Underground Laboratory in China on March 2016. In the same year in September, it was published as cover article at the Physical Review Letters in 2016, which has been cited more than 300 times. The United States LUX cooperation group published the final results of the past four years running on January 2017, and its sensitivity of the dark matter was more obvious than the PandaX-II. The XENON1T experiment in Italy released its first result in May this year, once again setting a world record for the limitation of dark matter. PandaX-II again released the results of the 2017 survey in August this year, once again leading international sensitivity. The results of PandaX-II and XENON1T were also published in the Physical Review Letters on November 3 (link: And is commented in Physics covered by the highest-rated "Viewpoint" (link:

Since 2013, Physics has started to mark the annual research highlights of International Physics. Selected achievements of the Chinese physics field in the past few years include the Beijing Spectrometer-III observing particles in the quark quadruple state (2013) and the first physical finding by the CAS Institute of Physics in Ferrets (2015).
