C.Maltoni, MicheleMartínez-Soler, IvánPinheiro, João PauloSchwetz, ThomasCP ViolationNeutrino Mixing33 pages, 13 figures, 3 tablesWe present an updated global analysis of neutrino oscillation data as of September 2024. The parameters theta12, theta13, Delta_m21^2, and |Delta_m3l^2 (l = 1,2) are well-determined with relative precision at 3 sigma of about 13%, 8%, 15%, and 6%, respectively. The third mixing angle theta23 still suffers from the octant ambiguity, with no clear indication of whether it is larger or smaller than 45 degrees. The determination of the leptonic CP phase deltaCP depends on the neutrino mass ordering: for normal ordering the global fit is consistent with CP conservation within 1 sigma, whereas for inverted ordering CP-violating values of deltaCP around 270 degrees are favored against CP conservation at more than 3.6 sigma. While the present data has in principle 2.5-3 sigma sensitivity to the neutrino mass ordering, there are different tendencies in the global data that reduce the discrimination power: T2K and NOvA appearance data individually favor normal ordering, but they are more consistent with each other for inverted ordering. Conversely, the joint determination of |Delta_m3l^2 from global disappearance data prefers normal ordering. Altogether, the global fit including long-baseline, reactor and IceCube atmospheric data results into an almost equally good fit for both orderings. Only when the chi^2 table for atmospheric neutrino data from Super-Kamiokande is added to our chi^2, the global fit prefers normal ordering with Delta_chi^2 = 6.1. We provide also updated ranges and correlations for the effective parameters sensitive to the absolute neutrino mass from beta-decay, neutrinoless double-beta decay, and cosmology.This project is funded by USA-NSF grant PHY-2210533 and by the European Union’s through the Horizon 2020 research and innovation program (Marie Skłodowska-Curie grant agreement 860881-HIDDeN) and the Horizon Europe research and innovation programme (Marie Skłodowska-Curie Staff Exchange grant agreement 101086085-ASYMMETRY), and by ERDF “A way of making Europe”.
