Probing the Majorana Nature of Neutrinos with nEXO

Speaker Dr. Raymond Hei-man Tsang
Affiliation Pacific Northwest National Laboratory for the nEXO Collaboration
Date December 11, 2018 (Tuesday)
Time 4:00 p.m.
Venue Room 522, 5/F, Chong Yuet Ming Physics Building, HKU

Abstract
 

The observation of neutrino oscillations has shown that neutrinos are in fact massive, contrary to the formulation in the Standard Model. This opens up the possibility to probe the Majorana nature of neutrinos – the property that neutrinos are their own anti-particles. The most promising approach is to search for neutrinoless double beta decay (0νββ). In this presentation, I will talk about the current status of the nEXO experiment, the successor to the EXO-200 experiment, which aims to continue the search for 0νββ of 136Xe. nEXO will employ a monolithic low background time projection chamber containing 5 tonnes of enriched liquid xenon. With 10 years of data, nEXO aims to reach a sensitivity of about 1028 years for a 0νββ half-life of 136Xe at 90% C.L., covering the inverted mass ordering region.

Coffee and tea will be served 20 minutes prior to the seminar.

Anyone interested is welcome to attend.
