lux zeplin Definition and 1 Threads
The LUX-ZEPLIN (LZ) Experiment is a next-generation dark matter direct detection experiment hoping to observe weakly interacting massive particles (WIMP) scatters on nuclei. It was formed in 2012 by combining the LUX and ZEPLIN groups. It is currently a collaboration of 30 institutes in the US, UK, Portugal and South Korea. The experiment is located at about 1,500 meteres under the Sanford Underground Research Facility (SURF) in South Dakota, and is managed by the United States Department of Energy's (DOE) Lawrence Berkeley National Lab (Berkeley Lab).
The experiment uses an ultra-sensitive detector made of 7 tonnes of liquid xenon to hunt for signals of WIMP-nucleus interactions. It is one of three such experiments which lead the search for direct detection of WIMPs above 10 GeV/c2, the other two being the XENONnT experiment and the PANDAX-4T experiment.
In the spring of 2015, LZ passed the "Critical Decision Step 1" or CD-1 review, and became an official DOE project. U.S. Department of Energy officials on Sept. 21, 2020 formally signed off on project completion for LZ; DOE's project completion milestone is called Critical Decision 4, or CD-4.

A Dark matter is running out of places to hide!
The second half of 2024 has seen the results from 3 years of data from the Lux Zeplin experiment in South Dakota, USA. Despite their attempts to put a positive spin on this, the bottom line is - no dark matter. Just three months before that the ATLAS experiment from CERN in Geneva, Switzerland...
