Title: Looking for More New Physics in Long-Baseline Oscillation Experiments
 
Abstract: Over the last couple of decades we discovered and started exploring the phenomenon of neutrino flavor oscillations. These revealed that neutrinos have nonzero masses and leptons mix. Many questions remain and many of them can only be realistically addressed with long-baseline neutrino oscillation experiments. Here, I will review what are these questions and will emphasize that they go beyond the search for CP-invariance violation in the lepton sector and precision measurements of the neutrino oscillation parameters - the main purpose of next-generation long-baseline experiments is to test whether our current understanding of the neutrino sector is not just adequate but also complete. I will discuss a few possibilities for what "other" new phenomena could be lurking in the neutrino-sector and will discuss a few case-studies that illustrate the reach of near-future experiments like DUNE and Hyper-Kamiokande.
