Current Status and Future Prospects of Three-Flavor Oscillations with Accelerator Neutrino Beams

The physics of neutrino oscillations has developed rapidly over the past few decades. Although there are still unmeasured parameters that determine this process. Measuring these parameters is the main goal of current and future projects in this area of particle physics. This review will discuss current neutrino accelerator experiments measuring three flavor neutrino oscillations (NOvA and T2K), and also briefly describe the prospects for future experiments (DUNE and Hyper-Kamiokande) and possible projects currently being considered.
