Global oscillation data analysis on the $3\nu$ mixing without unitarity

Understand

We present results of a combined analysis in neutrino oscillations without unitarity assumption in the $3\nu$ mixing picture.

• Constraints on neutrino mixing matrix elements are based on recent data from the reactor, solar and long-baseline accelerator neutrino oscillation experiments.
• The current data are consistent with the standard $3\nu$ scheme.
• The precision on different matrix elements can be as good as a few percent at $3\sigma$ CL, and is mainly limited by the experimental statistical uncertainty.
