Potential of octant degeneracy resolution in JUNO

This work extends the idea of using a cyclotron-based antineutrino source for purposes of neutrino physics. Long baseline experiments suffer from degeneracies and correlations between begin{document}$ Theta_{23} $end{document}, begin{document}$ delta_{rm CP} $end{document} and the mass hierarchy. However, the combination of a superconducting cyclotron and a big liquid scintillator detector like JUNO in a medium baseline experiment, which does not depend on the mass hierarchy, may allow to determine whether the position of the mixing angle begin{document}$ Theta_{23} $end{document} is in the lower octant or the upper octant. Such an experiment would improve the precision of the begin{document}$ Theta_{23} $end{document} measurement to a degree which depends on the CP-phase.
