MPPL Lecture 1 – To break CP or to not break CP – Hints for new CP violating physics in long baseline neutrino oscillations

The quest for leptonic CP violation is one of the major goals of near future neutrino oscillation experiments like DUNE and Hyper-Kamiokande. Experiments of the current generation like NOvA in the US and T2K in Japan do not have enough sensitivity to claim a significant discovery of CP violation however they provide already hints for the value of the CP violating quantity. Interestingly, their results currently mildly disagree with each other.

In this talk I will show how new physics effects can impact the measurement of CP violation in the neutrino sector. I will then show that the introduction of new CP violating neutrino interactions in matter can provide an explanation for the NOvA and T2K data and outline how the next generation of experiments can probe this solution.
