Advancing on the neutrino-nucleus interaction model

Uncertainties in neutrino-nucleus interactions are the most limiting experimental factor in the success of current and future neutrino oscillation experiments. This limitation has been, and still is, the cornerstone for the success of long-baseline experiments like T2K and HK. One of the world experts on this topic, Prof.

Kevin MacFarland, will be a visiting professor at the University of Geneva for the first six months of 2025. We have been collaborating for many years but have never had the opportunity to work closely for an extended period. The Geneva neutrino group is an international reference in this field, with numerous contributions.

Recently, we have concentrated on the search for new experimental observables that will allow us to identify weaknesses in our current models.

Their application to the new detectors recently installed in T2K will hopefully resolve some of the current uncertainties and help improve our models.
