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..

First measurement of the $\nu_e$ and $\nu_\mu$ interaction cross sections at the LHC with FASER’s emulsion detector / FASER Collaboration
This paper presents the first results of the study of high-energy electron and muon neutrino charged-current interactions in the FASER$\nu$ emulsion/tungsten detector of the FASER experiment at the LHC. A subset of the FASER$\nu$ volume, which corresponds to a target mass of 128.6~kg, was exposed to neutrinos from the LHC $pp$ collisions with a centre-of-mass energy of 13.6~TeV and an integrated luminosity of 9.5 fb$^{-1}$.

Neutrino Rate Predictions for FASER / FASER Collaboration
The Forward Search Experiment (FASER) at CERN's Large Hadron Collider (LHC) has recently directly detected the first collider neutrinos. Neutrinos play an important role in all FASER analyses, either as signal or background, and it is therefore essential to understand the neutrino event rates. [...]

Measurements of the $\nu_{\mu}$ and $\bar{\nu}_{\mu}$-induced coherent charged pion production cross cections on $^{12}C$ by the T2K experiment / T2K Collaboration
We report an updated measurement of the $\nu_{\mu}$-induced, and the first measurement of the $\bar{\nu}_{\mu}$-induced coherent charged pion production cross section on $^{12}C$ nuclei in the T2K experiment. This is measured in a restricted region of the final-state phase space for which $p_{\mu,\pi} > 0.2$ GeV, $\cos(\theta_{\mu}) > 0.8$ and $\cos(\theta_{\pi}) > 0.6$, and at a mean (anti)neutrino energy of 0.85 GeV using the T2K near detector.

The Hyper-K Underwater Electronics Assembly project / Hyper-Kamiokande Collaboration
Starting in 2027, the Hyper-Kamiokande experiment in Japan will search for leptonic CP violation in long-baseline accelerator neutrino oscillations with a realistic potential of discovery within 3 to 10 years from the start of the data taking depending on the value of the CP violating phase, to be measured with a resolution better than $23^{\circ}$.
