Welcome to the LZ dark matter experiment’s webpage!


LZ is a next-generation dark matter direct detection experiment. LZ has been selected to be one of three funded G2 dark matter experiments. The LZ collaboration consists of 128 scientists and engineers from 29 institutions in the U.S., U.K, Portugal, and Russia.

The LZ detector consists of 7 tonnes 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).
