The LUX-ZEPLIN experiment is a dark matter detector centered on dual-phase xenon time projection chamber operating at the Sanford Underground Research Facility in Lead, South Dakota, USA. This Letter reports results from LUX-ZEPLIN's first search for weakly interacting massive particles (WIMPs) with an exposure of 60~live days using fiducial mass 5.5 t. A profile-likelihood ratio analysis shows data to be consistent background-only hypothesis, setting new limits spin-independent...
High energy particle accelerators have been crucial in providing a deeper understanding of fundamental particles and the forces that govern their interactions. In order to increase or reduce size accelerator, new acceleration schemes need be developed. Plasma wakefield acceleration, which electrons plasma are excited, leading strong electric fields, is one such promising novel technique. Pioneering experiments shown an intense laser pulse electron bunch traversing plasma, drives fields 10s...
The nature of dark matter and properties neutrinos are among the most pressing issues in contemporary particle physics. dual-phase xenon time-projection chamber is leading technology to cover available parameter space for Weakly Interacting Massive Particles (WIMPs), while featuring extensive sensitivity many alternative candidates.
