The hypothetical track-length fitting algorithm for energy measurement in liquid argon TPCs / DUNE Collaboration
This paper introduces the hypothetical track-length fitting algorithm, a novel method for measuring the kinetic energies of ionizing particles in liquid argon time projection chambers (LArTPCs). The algorithm finds the most probable offset in track length for a track-like object by comparing the measured ionization density as a function of position with a theoretical prediction of the energy loss as a function of the energy, including models of electron recombination and detector response.

DUNE Phase II: scientific opportunities, detector concepts, technological solutions / DUNE Collaboration
The international collaboration designing and constructing the Deep Underground Neutrino Experiment (DUNE) at the Long-Baseline Neutrino Facility (LBNF) has developed a two-phase strategy toward the implementation of this leading-edge, large-scale science project. The 2023 report of the US Particle Physics Project Prioritization Panel (P5) reaffirmed this vision and strongly endorsed DUNE Phase I and Phase II, as did the European Strategy for Particle Physics.

First measurement of the total inelastic cross section of positively charged kaons on argon at energies between 5.0 and 7.5 GeV / DUNE Collaboration
ProtoDUNE Single-Phase (ProtoDUNE-SP) is a 770-ton liquid argon time projection chamber that operated in a hadron test beam at the CERN Neutrino Platform in 2018. We present a measurement of the total inelastic cross section of charged kaons on argon as a function of kaon energy using 6 and 7 GeV/$c$ beam momentum settings. [...]

Benchmarking neutrino interaction models via a comparative analysis of kinematic imbalance measurements from the T2K, MicroBooNE and MINERvA experiments / Filali, Wissal (CERN) ; Munteanu, Laura (CERN) ; Dolan, Stephen (CERN)
Recent neutrino-nucleus cross-section measurements of observables characterising kinematic imbalance from the T2K, MicroBooNE and MINERvA experiments are used to benchmark predictions from widely used neutrino interaction event generators. [...]

Combined Analysis of Neutrino and Antineutrino Charged Current Inclusive Interactions / Franco-Patino, Juan M (Seville U.) ; Gacino-Olmedo, Alejandro N (Seville U. ; CERN) ; Gonzalez-Rosa, Jesus (Seville U.) ; Dolan, Stephen J (CERN) ; Megias, Guillermo D (Seville U.) ; Munteanu, Laura (CERN) ; Barbaro, Maria B (INFN, Turin ; Turin U.) ; Caballero, Juan A (Seville U.)
This paper presents a combined analysis of muon neutrino and antineutrino charged-current cross sections at kinematics of relevance for the T2K, MINERvA and MicroBooNE experiments. We analyze the sum, difference and asymmetry of neutrino versus antineutrino cross sections in order to get a better understanding of the nuclear effects involved in these processes. [...]

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..
