Description
The Jiangmen Underground Neutrino Observatory (JUNO) is a 20 kt liquid scintillator detector with the main goal to determine the neutrino mass ordering. To reach this goal, JUNO is designed to have an energy resolution of 3%/$\sqrt{𝐸(\text{MeV})}$ and it will measure the reactor neutrino spectrum from two nuclear power plants located in a distance of around 53 km from the detector. One crucial aspect for the success of JUNO is the precise knowledge of the emitted reactor neutrino spectrum. In recent years, new calculations of the reactor neutrino spectrum predicted the possible existence of a spectral finestructure which has not been measured before due to the insufficient energy resolution of previous experiments. With the unprecedented energy resolution of the JUNO detector, possible implications of this finestructure on the sensitivity to determine the neutrino mass ordering have to be investigated.
This contribution will present possibilities to study the implications of the still unknown finestructure in the reactor neutrino spectrum for JUNO’s neutrino mass ordering sensitivity. Further, the potential of JUNO’s satellite detector TAO to reduce a possible impact of the finestructure will be discussed.
