Determining Neutrino Mass Ordering with NOvA and Upcoming JUNO Measurements

Abstract

NOvA has reported a significance of mass ordering determination using ten years of data together with external constraints from reactor-based experiments. The JUNO collaboration is poised to provide a more precise reactor-based constraint on $|\hat{I}”m_{32}^2|$. In this Letter, we explore the potential impact of this anticipated measurement on the determination of the neutrino mass ordering by NOvA. We find that $3\ddot{I}ƒ$ evidence of the normal ordering is achievable over a range of plausible JUNO measurements within the next five years.
