Description
LUX-ZEPLIN (LZ) is a direct detection experiment with the primary aim of searching for Weakly Interacting Massive Particles (WIMPs), one of the leading candidates for dark matter. Central to this search is the ability to identify and distinguish signals from any background events, with neutron induced signals presenting a particular challenge due to their similarity to those produced by WIMPs. The Outer Detector (OD) plays a critical role in this effort by identifying and vetoing such neutron events. In order for this to be done effectively, accurate energy calibrations are required, as well as a thorough understanding of the detector’s neutron-tagging efficiency. The ongoing monitoring of the outer detector is also crucial in ensuring performance is consistent and high levels of precision are maintained. Such monitoring includes studies of single photoelectron responses, after-pulsing effects, and analysis of detector stability over time. This talk will explore how these efforts support high sensitivity of the LZ experiment to WIMP search and other effects beyond the standard model.
