First JUNO Data Pinpoints Neutrino Oscillation Parameters with High Precision

JUNO's first 59.1 days of data from a 20-kton detector at 52.5 km from reactors yield a simultaneous, high-precision measurement of sin^2θ12 = 0.3092 ± 0.0087 and Δm21^2 = (7.50 ± 0.12)×10^-5 eV^2 for the normal mass ordering, improving precision by a factor of 1.6 over previous measurements and validating JUNO's design and energy calibration while showing readiness to determine the neutrino mass hierarchy with more data.

Global Study Unveils New Insights into Neutrinos and Matter's Existence

A joint analysis of neutrino oscillation data from the T2K and NOvA experiments provides improved constraints on oscillation parameters, including the mixing angle θ23, mass-squared difference Δm32², and the CP-violating phase δCP, with no significant preference for either mass ordering but evidence suggesting potential CP violation, especially under the inverted mass ordering assumption.
