    Synergies and prospects for early resolution of the neutrino mass ordering

  • Original language description

    The measurement of neutrino mass ordering (MO) is a fundamental element for the understanding of leptonic flavour sector of the Standard Model of Particle Physics. Its determination relies on the precise measurement of Delta m(31)(2) and Delta m(32)(2) using either neutrino vacuum oscillations, such as the ones studied by medium baseline reactor experiments, or matter effect modified oscillations such as those manifesting in long-baseline neutrino beams (LB nu B) or atmospheric neutrino experiments. Despite existing MO indication today, a fully resolved MO measurement (&gt;= 5 sigma) is most likely to await for the next generation of neutrino experiments: JUNO, whose stand-alone sensitivity is similar to 3 sigma, or LB nu B experiments (DUNE and Hyper-Kamiokande). Upcoming atmospheric neutrino experiments are also expected to provide precious information. In this work, we study the possible context for the earliest full MO resolution. A firm resolution is possible even before 2028, exploiting mainly vacuum oscillation, upon the combination of JUNO and the current generation of LB nu B experiments (NOvA and T2K). This opportunity is possible thanks to a powerful synergy boosting the overall sensitivity where the sub-percent precision of Delta m(32)(2) by LB nu B experiments is found to be the leading order term for the MO earliest discovery. We also found that the comparison between matter and vacuum driven oscillation results enables unique discovery potential for physics beyond the Standard Model.
