Probing the octant of ${\theta }_{23}$ with very long baseline neutrino oscillation experiments: a global look

Guey-Lin Lin, Yoshiaki Umeda

We investigate the baseline range in which the ${\theta }_{23}$ degeneracy in neutrino oscillation probabilities is absent for fixed values of ${\theta }_{13}$ and CP violation phase ${\delta }_{\mathrm{CP}}$.…
