Recent results of the EXO-200 neutrinoless double-beta decay experiment
Dr. Michael Marino (TUM, Excellence Cluster Universe)
Neutrinoless double-beta decay provides a strong probe of physics beyond the standard model. The observation of such a decay would establish that the neutrino and anti-neutrino are the same particle - a so-called Majorana particle - and would help determine the absolute mass scale of the neutrino. In addition, it could provide insight into understanding
lepton-number-violating processes, helping to illuminate causes of the observed matter-anti-matter asymmetry in the universe. The Enriched Xenon Observatory (EXO) experiment employs an enriched liquid-xenon Time Projection Chamber (TPC) deployed underground at the Waste Isolation Pilot Plant (WIPP) in New Mexico, USA, to search for the neutrinoless double-beta decay of Xe-136. An overview of the EXO experiment will be given and recent results will be discussed establishing limits on the neutrinoless double-beta decay of Xe-136.
