This market will resolve to YES if the LUX-ZEPLIN (LZ) collaboration officially announces the discovery or confirmed direct detection of a Weakly Interacting Massive Particle (WIMP) (or another dark matter particle candidate) with a statistical significance of 5-sigma ($\ge 5\sigma$) or greater by December 31, 2027.
If no such 5-sigma confirmation is announced by the LZ collaboration by the end of December 31, 2027, this market will resolve to NO.
Language in the announcement that makes some hedges but implies strongly it is some sort of WIMP will count as yes, I will use my judgement. I will not participate in this market.
1,000If the new result is real, more signals should emerge soon. LZ researchers have already collected three times as much data as they used in the paper. And other detectors, such as XENONnT in Italy’s Gran Sasso National Laboratory, which is nearly as big as LZ, or the far bigger next version of the PandaX detector, currently under development in China, should be able to search for the high energy events, too.
