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 (CD-1)’ or
CD-1 review, and became an official DOE project.
In August 2016, LZ passed the ‘Critical Decision Step 2 (CD-2)’ and formalized the baseline project.
In February 2017, the project passed a DOE review and approval stage known as `Critical Decision 3 (CD-3)’, which accepts the final design and formally launches construction.
In March 2017, we published our Technical Design Report (CDR) at arXiv: 1703.09144.
The LZ collaboration consists of about 250 scientists in 37 institutions in the U.S., U.K., Portugal, Russia, 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.
