Future of neutrino experiments

Atmospheric, solar, reactor and accelerator neutrino oscillation experiments have measured Δm ₁₂², sin² θ ₁₂, |Δm ₂₃²| and sin² 2θ ₂₃. The next stage of the oscillation studies should be the observation of a finite sin² 2θ ₁₃. If a non-zero sin² 2θ ₁₃ is observed, the subsequent goals should be the observation of the CP violation and the determination sign of Δm ₂₃². Possible future neutrino oscillation experiments that could assess these questions are discussed.
