TITLE: Neutrino interactions: a challenge for T2K and beyond


Neutrino oscillations offer a unique opportunity to explore physics beyond the Standard Model. Multiple current and planned experiments aim at precisely characterizing these oscillations with neutrinos artificially produced in accelerators. This is the case of the T2K experiment, located in Japan, which provides one of the world-leading constraints on how neutrinos oscillate.
An important obstacle in the making of such results is the modeling of neutrino interactions which could bias oscillation measurements. Indeed, the uncertainties associated with neutrino-nucleus interactions are difficult to quantify and constrain as they cover a large range of poorly-understood nuclear physics of how neutrinos interact.

In this seminar, I will present how accelerator-based neutrino experiments measure these oscillations, with a focus on how we tackle the challenge of modeling neutrino-nucleus interactions in the T2K experiment. Furthermore, I will show how the ongoing upgrade of the T2K near detector will provide valuable information to significantly improve our understanding of neutrino interactions. Finally, I will discuss the prospects of overcoming this challenge in the context of the next-generation experiment DUNE.
