Description

The Jiangmen Underground Neutrino Observatory (JUNO) is a medium-baseline reactor neutrino experiment currently under construction in southern China. $20\mathrm{kton}$ LAB-based liquid scintillator target is contained inside the Central Detector, a $35.4\mathrm{m}$ diameter spherical acrylic vessel. The scintillator light emitted from the Central Detector will be read out by the surrounding $1761220”$ and $256003”$ photo-multiplier tubes, which are submerged inside a $40\mathrm{m}$ diameter cylindrical water pool acting as an active shielding detector. The main goal of JUNO will be the determination of the neutrino mass ordering at a statistical significance of about $3\sigma$ within $6\mathrm{years}$ of data-taking using electron anti-neutrinos produced in two nuclear power plants at a distance of $\sim 52.5\mathrm{km}$. To achieve this, JUNO aims for an unprecedented $3\mathrm{\%}$ energy resolution at $1\mathrm{MeV}$. This resolution together with the detector’s low energy threshold will enable a broad physics program including the observation of solar neutrinos, geo-neutrinos, neutrinos from a close by core-collapse supernova and the diffuse supernovae neutrino background as well as competitive sensitivity to proton decay. Additionally, JUNO will be able to determine the neutrino oscillation parameters ${\sin }^2({\theta }_{12}),\mathrm{\Delta }{m}_{21}^2$ and $\mathrm{\Delta }{m}_{31}^2$ at the sub-percent level. The talk will present the design of the experiment, its status and its physics prospects.
