Description

LUX-ZEPLIN (LZ) is a direct dark matter detection experiment aiming to detect rare events resulting from the scattering of Weakly Interacting Massive Particles (WIMPs). It employs a dual-phase xenon time projection chamber (TPC) with an active mass of 7 tonnes (5.6 tonne fiducial), surrounded by an instrumented xenon skin and liquid scintillator active vetoes. Significant effort has been made to achieve an unprecedented low background rate within its fiducial volume, including extensive detector material screenings, an inline radon removal system, and in-house xenon purification, to reach a target sensitivity of 1.4 x 10$^{-48}$ cm2 at 40 GeV/c$^2$. This talk will detail the backgrounds for the first LZ WIMP search results.
