LZ Released First Science Results!
A profile-likelihood analysis shows the data to be consistent with a background-only hypothesis, setting new limits on spin-independent WIMP-nucleon cross-sections for WIMP masses above 9 GeV/c2. The most stringent limit is set at 30 GeV/c2 excluding cross sections above 5.9×10-48cm2 at the 90% confidence level.
Our group is currently involved in a research collaboration called LZ, a 10 tonne liquid xenon experiment almost 1 mile underground at the Sanford Underground Laboratory in South Dakota.
Congratulations to Will Taylor on completing his PhD thesis Neutron Calibrations and Activation Signals in Low-Background Liquid Xenon Dark Matter Detectors!
