The neutrino mass is the only laboratory measurement that violates the Standard Model and it is one of our best bets for a glimpse of the physics that lies beyond it. In particular, it leads naturally to the possibility that the neutrino is a Majorana particle. Equal to their anti-partners, Majorana neutrinos could explain the neutrino mass scale and the matter-antimatter asymmetry in today's universe. For answering this pressing question, our only handle is the observation of neutrinoless double beta decays (0vbb).
Currently taking background water data, the SNO+ experiment aims for world leading 0vbb sensitivity using 1.3 tonne of Te130 loaded into a kilotonne scale liquid scintillator detector. Here we review the experiment's progress and sensitivity, making the case for Te130 and large liquid scintillator experiments for probing the inverted hierarchy and beyond.
The experimental particle physics seminar series invites speakers from all over Europe to discuss the latest developments at the LHC, accelerator and non-accelerator based neutrino physics, hardware R&D and astroparticle physics. .
