Search for new physics beyond Standard Model with the LZ experiment
ORAL
Abstract
LUX-ZEPLIN (LZ), located at the Sanford Underground Research Facility, is a world leading direct detection experiment in the search for dark matter. At its core is a dual-phase xenon time projection chamber containing 7 tonnes of active liquid xenon, surrounded by two active veto systems. Having recently reported world-leading constraints on WIMP dark matter, LZ's exceptional sensitivity also enables the exploration of a broad range of other beyond the Standard Model (BSM) physics. In this talk, I will present the latest results from dedicated searches for exotic, non-WIMP phenomena, based on a total exposure of 4.2 ± 0.1 tonne-years. This talk will cover a diverse set of representative BSM physics models, including atmospheric millicharged particles, cosmic-boosted, and solar axion-like particles.
