Will we know the Neutrino Mass Ordering by the end of 2026?

The JUNO reactor neutrino experiment has recently begun collecting data, marking the start of a new precision era in neutrino research. With its unparalleled precision, JUNO is poised to refine our understanding of most neutrino oscillation parameters. Its cornerstone measurement -- the determination of the neutrino mass ordering -- holds the promise of a breakthrough. In this talk we will explore the physics behind the two distinct ways JUNO data can be used to probe the mass ordering, one of which could lead to the resolution of this fundamental question in the near future. Additionally, we will examine the conditions necessary for such a discovery and address potential theoretical caveats that could influence the interpretation of the outcome.
