No Statistically Significant Evidence Of Dark Matter At XENON1T

A new paper goes to great length to describe the results of dark matter searches at XENON1T. 

All hints of a signal of dark matter in excess of the expected background results had a local significance of less than 2 sigma (1.7 sigma and 1.8 sigma in two of many bins of the parameter space studied), which is not statistically significant. The significance would have been even lower had the look elsewhere effect been considered.
