Description
The LUX-ZEPLIN (LZ) dark matter experiment is located at a depth of about 4850 feet at Sanford Underground Research Facility (South Dakota, USA). The LZ detector constitutes a dual-phase time projection chamber with a 7-tonne liquid xenon target. Weakly Interacting Massive Particles (WIMPs), well motivated dark matter candidates, are expected to produce nuclear recoils while interacting with the target medium, giving a detectable signal. Although no evidence of WIMPs has yet been found, LZ has been able to set world leading limits on the interaction cross-section of such a particle over a wide range of masses. In this talk, I will present the results of the recent LZ search for light dark matter and our 4.5𝜎 detection of solar B8 neutrinos, the first >3𝜎 detection of the neutrino fog.
