Neutrino experiments at the LHC such as FASER$\nu$, SND@LHC and potentially the FPF will detect neutrinos at the energy range of a few GeV to a few TeV. In neutrino scattering, there is a transition region from the so-called shallow inelastic scattering (SIS) to deep inelastic scattering (DIS). Although the boundary of the SIS and DIS is not clearly defined, the SIS region is generally...
Within the framework of a relativisitic mean-field approach, I will discuss some relevant nuclear effects that affect neutrino-nucleus cross sections at the energies of interest for neutrino-oscillation experiments, such as Pauli blocking, binding energies and hadron final state interactions. I will stress the differences between this relativistic and quantum mechanical approach and the models...
The NINJA experiment aims to study neutrino-nucleus interactions in the 1 GeV energy region with a nuclear emulsion-based detector. The nuclear emulsion is suitable for measuring the positions and angles of charged particles from neutrino interactions since it has a sub-µm spatial resolution. The sub-micron spatial resolution of the emulsion detector allows us to detect short tracks of...

Reliable modeling of quasielastic (QE) lepton scattering on nuclei is of great interest to neutrino oscillations experiments, especially at low values of the 3-momentum transfer $\bf \vec q$. We report on a phenomenological fit to all available electron scattering data on $\rm ^{12}_6C$ (about 8000 differential cross section measurements) and $\rm ^{12}_OC$ (about 250 measurements) within...
In order to achieve the ambitious goal of characterising neutrino flavour oscillations with percent-level precision, it is critical for current and future long-baseline neutrino oscillation experiments to substantially reduce existing systematic uncertainties. The most challenging of such systematic uncertainties is related with the modelling few-GeV neutrino-nucleus interactions.
To...

In current measurements of accelerator-based neutrino experiments, neutrino flux uncertainties represent a leading systematic uncertainty. Neutrino beams are created from the decays of secondary hadrons produced in hadron-nucleus interactions. Primary and secondary hadron production processes for neutrino beams are the leading source of flux uncertainty. Therefore, precise hadron production...
One of the leading sources of systematic uncertainty in neutrino experiments is the modeling of the neutrino flux. Neutrino flux uncertainties are dominated by hadron scattering and hadron production cross section uncertainties, and new, dedicated measurements are needed. The EMPHATIC collaboration aims to measure the forward-scattering and production of hadrons for a variety of beam momenta...
The main source of systematic uncertainty on neutrino cross section measurements at the GeV scale is represented by the poor knowledge of the initial flux. The goal of cutting down this uncertainty to 1% can be achieved through the monitoring of charged leptons produced in association with neutrinos, by properly instrumenting the decay region of a conventional narrow-band neutrino beam. Large...
The low-nu method has been discussed as a "standard candle" in the context of accelerator neutrino beam experiments which require a precise understanding of the neutrino flux. The method utilizes a sub-sample of events where there is low energy-transfer to the nucleus, and requires that the interaction cross section is approximately constant for this sub-sample as a function of neutrino...
This talk will cover two different analyses of muon neutrino charged current interactions on a CH target, as recorded by MINERvA in the NuMI Medium Energy beam. The first analysis focuses on the 0-pion data set which has the advantage that the recoil energy in this set is dominated by the sum of the kinetic energies of the protons that are ejected from the target nucleus. Because of the...
The MINERvA experiment at Fermilab presents results from several analyses of quasielastic-like (QE-like) $\nu_{\mu}$ interactions on a variety of nuclear targets in the NuMI neutrino beams.

Next generation neutrino oscillation experiments are poised to provide answers to key questions about the nature of the neutrino. The axial form factor is a vital ingredient in the nucleon amplitudes used to predict quasielastic scattering, a primary signal measurement process for flagship neutrino oscillation experiments, yet the uncertainty on this form factor is vastly underestimated by the...
The next generation of neutrino oscillation experiments require precise predictions of neutrino-nucleus cross sections as well as control over their uncertainties, including the contribution of model dependence to the overall error budget. To this end we compare two methods of computing $CC0\pi$ flux folded cross sections; an ab-initio method based on Greens Function Monte Carlo, and a Quantum...

The enormous flux of neutrinos the NuMI's medium energy beam enables a number of new measurements of coherent and incoherent pion production on MINERvA's scintillator and passive carbon, water, iron, and lead targets. These measurements show a number of discrepancies with current generator models, and provide information about the correct scaling of single pion production with different...
Long-baseline neutrino oscillation experiments rely on detailed models of neutrino interactions on nuclei. These models constitute an important source of systematic uncertainty, in part because current detectors have been blind to final state neutrons.
