Description
Neutrinos are the only known fermions with zero electric charge, and thus far the unique candidates to act as their own antimatter counterpart. If indeed a neutrino is its own antiparticle, we can find processes in which lepton number conservation, a global symmetry of the Standard Model, is violated. Such a discovery would have great implications in neutrino physics and their interactions. The most sensitive test for this condition, also known as Majorana neutrinos, is through the search of a hypothetical decay known as neutrinoless double beta decay. The primary focus of the nEXO Collaboration is the search for this process using a liquid xenon time projection chamber, at the tonne-scale rooted on the success of the EXO-200 experiment. Our projections result in a half-life sensitivity beyond $10^{28}$ yr, sufficient to cover a milestone of this search consisting of the inverted ordering of neutrinos masses. This poster presents the search as well as the nEXO detector and its potential for discovery of new physics.
