Systematics UNcertainties in Combinations of neutrino Oscillation Results – SUNCORE

Submission summary

The field of neutrino oscillations is entering the precision era: the three mixing angles are known and the community is trying to measure CP violation in the leptonic sector. Such measurement can only be done by observing the appearance of neutrinos of different flavors in long baseline experiments in which muon neutrinos are produced by an accelerator and the transition to electron neutrinos is observed with far detectors hundreds of km away. In order to observe CP violation the appearance probabilities for neutrinos and antineutrinos have to be carefully compared. The growing statistics accumulated by running experiments such as T2K calls for a better understanding of the systematic uncertainties that are dominated by uncertainties on neutrino fluxes and neutrino cross-sections. The goal of SUNCORE is to reduce these two sources of uncertainties in order to do early measurements of CP violation with T2K, with the combination between T2K, NOVA and SK and pave the way to precision measurements with future experiments (HK and DUNE).
