Description
The Jiangmen Underground Neutrino Observatory (JUNO) is a multi-purpose neutrino observatory under construction in China. It will host a 20 kt liquid scintillator detector underground with an overburden of 700 m to study the neutrinos from different neutrino sources. With an unprecedented energy resolution of 3% at 1 MeV, JUNO is designed mainly to detect the anti-neutrinos from the nuclear power plants located $\approx$ 53 km from the detector. One of the main physics goals of the experiment is to determine the neutrino mass ordering (MO) and to precisely measure the neutrino oscillation parameters $\Delta m^2_{21}$, $\sin^2\theta_{12}$, and $\Delta m^2_{31}$ using the reactor anti-neutrino flux. It is estimated that using six years of data, JUNO will determine the neutrino MO with a significance of $3\sigma$ and also determine the parameter $\Delta m^2_{31}$ with a precision of $\approx 0.2\%$. Meanwhile, the parameters $\Delta m^2_{21}$ and $\sin^2\theta_{12}$ will be determined with a precision of $\approx 0.3\%$ and $\approx 0.5\%$ respectively. The results from JUNO are expected to improve upon the existing knowledge of precision on these three parameters by almost one order of magnitude. Additionally, JUNO can also measure neutrino oscillations using solar and atmospheric neutrinos. This talk will mainly report on the physics of neutrino oscillations with the reactor neutrinos at JUNO, and discuss the analysis strategy used in estimating these parameter sensitivities.
