Welcome to the LZ dark matter experiment’s webpage!

LZ is a next generation dark matter experiment.  LZ 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.   In the spring of 2015, LZ passed the ‘Critical Decision Step 1’ or
CD-1 review, and became an official DOE project.

We have just published our Conceptual Design Report(CDR), which was prepared for CD-1. The CDR is also available as arXiv:1509.02910 [physics.ins-det].

The LZ collaboration consists of 190 scientists in 32 institutions in the U.S., U.K., Portugal, Russia, and China.

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).
