LZ Dark Matter

Experiment
About Us

LUX-ZEPLIN (LZ) is a flagship physics experiment searching for the elusive dark matter particles which many scientists believe make up most of the mass of the universe.

The LZ detector employs a 7-tonne liquid xenon target to search for the rare interactions of these particles with ordinary atoms in the detector medium. The experiment is located one mile underground at the Sanford Underground Research Facility (Lead, South Dakota, USA).

This is the website for LZUK, the collaboration of nine UK institutes working on LZ. The website for the international project can be found here.
