The Super Fine-Grained Detector (SuperFGD) for the T2K neutrino oscillation experiment
/ Sgalaberna, Davide (speaker) (ETH Zurich (CH))
T2K is a long-baseline neutrino oscillation experiment in Japan that searches for leptonic CP violation. The magnetised near detector (ND280) has the role of constraining the dominant systematic uncertainties, related to the neutrino flux and interaction cross section, in the measurement of the neutrino oscillation probability.

This letter presents the measurement of the energy-dependent neutrino-nucleon cross section in tungsten and the differential flux of muon neutrinos and anti-neutrinos. The analysis is performed using proton-proton collision data at a center-of-mass energy of 13.6 TeV and corresponding to an integrated luminosity of (65.6 ± 1.4) fb−1. [...]

The impact of nuclear effect modeling on the cross-section ratio $\nu_e/\nu_\mu$ and its impact for futrue measurements of CP violation
/ Dieminger, T (Zurich, ETH) ; Dolan, S (CERN) ; Sgalaberna, D (Zurich, ETH) ; Nikolakopoulos, A (Fermilab) ; Dealtry, T (Lancaster U.) ; Bolognesi, S (IRFU, Saclay) ; Pickering, L (Royal Holloway, U. of London) ; Rubbia, A (Zurich, ETH)
Long-baseline (LBL) neutrino oscillation experiments search for Charge-Parity (CP) violation in the leptonic sector by precisely measuring the $\nu_\mu\to\nu_e$ and $\overline{\nu}_\mu\to\overline{\nu}_e$ appearance probabilities.One of the dominant systematic uncertainties on the measurements of CP violation, comes from our modeling of the $\nu_e/\overline{\nu}_e$ cross-section ratio, which is subject to a range of uncertainties related to poorly-constrained nuclear physics processes.Whilst tight constraints on the $\nu_\mu/\overline{\nu}_\mu$ cross-section can be achieved using LBL experiment's near detector data, the lepton mass differences mean that the extrapolation to the $\nu_e/\overline{\nu}_e$ is not trivial.Currently running LBL experiments reach a sensitivity to exclude the CP conserving hypothesis of about three standard deviations for a relatively large range of $\delta_{CP}$ values, hence a more accurate evaluation of the $\nu_e/\overline{\nu}_e$ related uncertainties becomes increasingly crucial.Following up on work by Nikolakopoulos et al.~\cite{Nik}, we present the analysis from \cite{UncertaintiesOTDi}, quantifying the potential for miss-modelling of the $\nu_\mu/\nu_e, \ \overline{\nu}_\mu / \overline{\nu}_e$ and $\nu_e/\overline{\nu}_e$ cross sections due to nuclear effects as a model spread in the full kinematic phase space for CCQE interactions.This impact is then propagated to simulated experimental configurations based on the Hyper-K and ESS$\nu$SB experiments.Significant differences between the theoretical models are found, which largely lie in regions of phase space that contribute only a small portion of the flux integrated cross sections.Overall, a systematic uncertainty on the oscillated flux-averaged $\nu_e/\overline{\nu}_e$ cross section of $\sim 2$\% and $\sim4$\% is found for the simulated Hyper-K and ESS$\nu$SB experiments respectively..

Long-baseline neutrino oscillation experiments rely on detailed models of neutrino interactions on nuclei. These models constitute an important source of systematic uncertainty, partially because detectors to date have been unable to detect final state neutrons. [...]

Present and next generation of long-baseline accelerator experiments are bringing the measurement of neutrino oscillations into the precision era with ever-increasing statistics. One of the most challenging aspects of achieving such measurements is developing relevant systematic uncertainties in the modeling of nuclear effects in neutrino-nucleus interactions. [...]

Longitudinal kinematic imbalances in neutrino and antineutrino interactions for improved measurements of neutrino energy and the axial vector form factor
/ Baudis, Nathan (Zurich, ETH) ; Dolan, Stephen (CERN) ; Sgalaberna, Davide (Zurich, ETH) ; Bolognesi, Sara (IRFU, Saclay) ; Munteanu, Laura (CERN) ; Dieminger, Till (Zurich, ETH)
Current and future accelerator neutrino oscillation experiments require an improved understanding of nuclear effects in neutrino-nucleus interactions. One important systematic uncertainty is introduced by the collective impact of nuclear effects which bias the reconstruction of the neutrino energy, such as the nuclear removal energy. [...]
