We examine accuracy of theta_{23} determination in future long-baseline (LBL) nu_{mu} disappearance experiments in the three-flavor mixing scheme of neutrinos. Despite that the error of sin^2{2theta_{23}} is indeed a few % level at around…

Neutrinos described as an open quantum system may interact with the environment which introduces stochastic perturbations to their quantum phase. This mechanism leads to a loss of coherence along the propagation of the neutrino $-$ a…
The octant of the atmospheric mixing angle $\theta_{23}$ is still undetermined by neutrino oscillation experiments. Long-baseline experiments like NO$\nu$A, T2K and DUNE offer good prospects for determining the octant of $\theta_{23}$.…
