Update on non-unitary mixing in the recent NOνA and T2K data

In this paper, we have tested the non-unitary mixing hypothesis with the latest data from NOνA and T2K experiments. We have also analysed their combined data. We have provided the best-fit values of the standard and non standard parameters after the analysis. 90% limits on the non-unitary mixing parameters have also been provided. The constraints on unitary violation is stronger, compared to the constraints obtained from previous data from NOνA and T2K. The tension between NOνA and T2K at the 1 σ for normal mass hierarchy can be reduced for non-unitary mixing due to α10, albeit for a value of |α10| larger than the present global 90% limit. Additionally a study of the future sensitivity of NOνA, T2K and DUNE has been provided.
