Experimental Particle Physics seminar: “EXO-200 recent results and nEXO outlook”

The discovery of neutrino mass is direct evidence of physics beyond the Standard Model. It is an experimentally open question whether neutrinos have Majorana masses, and neutrinoless double beta decay is the most promising experimental technique to search for Majorana neutrinos. EXO-200 and nEXO are part of a program to search for neutrinoless double beta decay of Xe-136 using single phase liquid xenon time projection chamber technology. I will report on recent results from the EXO-200 experiment, which ran from 2011 to 2018 at the Waste Isolation Pilot Plant in Carlsbad, NM. I will also discuss technical progress toward nEXO, a next generation experiment with a projected 10-year half-life sensitivity of 1.35x1028  yr at 90% confidence level.
