LZ (LuxZeplin) is a next generation dark matter experiment. It has been selected by the US Department of Energy (DOE) and the US National Science Foundation as one of the three ‘G2’ (for Generation 2) dark matter experiments.

The LZ collaboration consists of about 250 scientists in 35 institutions in the U.S., U.K., Portugal, and Korea.

The LZ detector consists of 10 tonnes total of liquified xenon to detect faint interactions between galactic dark matter and regular matter. Dark matter comprises about 85% of the mass of the Universe, and its particle nature is still unknown.

The name LZ stems from the merger of two dark matter detection experiments: LUX (Large Underground Xenon) and ZEPLIN (ZonEd Proportional scintillation in LIquid Noble gases).
