Improved Sensitivity of nEXO to Neutrinoless Double Beta Decay

ORAL

Abstract

The nEXO detector is the next generation of neutrinoless double beta decay of Xe-136. The 5-ton liquid xenon TPC detector is based on the EXO-200 experiment. The nEXO experiment has developed a baseline design with a projected half-life sensitivity two orders of magnitude greater than previous experimental results. This talk will discuss the results of the sensitivity simulation and calculation for the nEXO detector published in 2018. Improvements on the initial simulation will also be discussed. These include expanding the event reconstruction and background identification to include the skin LXe, charge and light collection, and time correlated decays.
