Description
The Jiangmen Underground Neutrino Observatory (JUNO) is a 20 kton multi‑purpose underground liquid scintillator detector currently under construction at a baseline of about 52.5 km from eight nuclear reactors in the Guangdong Province of South China. By featuring a 78% photon sensor coverage achieved via a primary calorimetry system consisting of 17,612 20‑inch PMTs and an additional calorimetry system of 25,600 3‑inch PMTs, JUNO is expected to enable an unprecedented 3% energy resolution at 1 MeV scale, aiming at the determination of the neutrino mass ordering. Besides its main ambitious goal, JUNO's extensive physics program includes studies of neutrinos from the Sun, the atmosphere, supernovae, and planet Earth, as well as explorations of physics beyond the Standard Model.
In this respect, thanks to its unparalleled size and energy resolution, JUNO will enable the simultaneous observation of the $\Delta m_{31}^{2}$, $\Delta m_{21}^{2}$, $\sin^{2}\theta_{12}$, and $\sin^{2}\theta_{13}$ oscillation parameters and is expected to determine the first three to a world‑leading precision better than 0.6% within six years of data taking. The unmatched sub-percent precision on the oscillation parameters will permit JUNO to scrutinize the unitarity of the 3×3 Pontecorvo-Maki-Nakagawa-Sakata matrix describing neutrino
mixing, fundamental to probe and constrain the flavor mixing parameters associated to possible new physics, and possibly shedding light on the underlying dynamics responsible for neutrino mass generation and lepton flavor mixing. In this talk I will present the role of JUNO in a new era of precision in the neutrino sector which will pave a way to potentially discover physics beyond the Standard Model.
