The long-baseline neutrino oscillation experiments T2K (Tokai to Kamioka) in Japan and NOvA in the United States have recently performed a joint analysis, providing the most precise measurement to date of ∆m^2_32= 2.48_0.03^0.04 × 10⁻³ eV² in inverted ordering. Achieving this level of precision requires careful control of systematic uncertainties, particularly those associated with the modelling of neutrino–nucleus interactions. This seminar will present an overview of neutrino interaction modelling and discuss the strategies used to constrain the associated uncertainties in long-baseline oscillation analyses.
About the speaker:
Kamil is a Postdoctoral Research Associate at Royal Holloway, University of London. His research focuses on the T2K long-baseline neutrino oscillation experiment, where he serves as a convener of the Neutrino Interaction Working Group, contributing to improvements in the modelling of neutrino interactions. He is also involved in T2K oscillation analyses, with a particular focus on the near detector, which plays a key role in reducing systematic uncertainties and enabling high-precision oscillation measurements. Constraining these uncertainties using near-detector data was the central topic of his PhD research.
