According to the recent results of the neutrino oscillation experiment MINOS, the neutrino mixing angle θ 23 may not be maximal (45°). Two nearly degenerate solutions are possible, one in the lower octant (LO) where θ 23 < 45°, and one in the higher octant (HO) where θ 23 > 45°. Long baseline experiments measuring the ν μ → ν e are capable of resolving this degeneracy. In this work we study the potential of the planned European LBNO experiment to distinguish between the LO and HO solutions.
