I will discuss recent advances on the description of lepton-nucleus interactions in the energy region relevant for oscillation experiments. Various methods employing Quantum Monte Carlo techniques have been employed to derive the presented results.
The study of neutrino-nucleus scattering processes is important for the success of a new generation of neutrino experiments such as DUNE and T2K. Quasielastic neutrino-nucleus scattering, which yields a final state consisting of a nucleon and charged lepton, makes up a large part of the total neutrino cross-section in neutrino experiments. A significant source of uncertainty in the...
The hadronic responses and inclusive cross sections for lepton-nucleus scattering are computed within an independent-particle relativistic mean field model to describe the initial and final states, and one- and two-body current operators leading to the one-nucleon knockout reaction. The two-body currents produce an increase in the tranverse sector that improves the agreement with data,...
We report on comparison of the predictions of neutrino event generators (run in electron scattering mode) to a recent global extraction of the 12C and 40Ca Longitudinal (RL) and Transverse (RT ) nuclear electromagnetic response functions from an analysis of all available electron scattering dats on carbon and calcium. The response functions are extracted for a large range of energy transfer ν,...
We present the combination of the SuSAv2 and dynamical coupled-channels (DCC) models. The DCC model, an approach to study baryon resonances through electron and neutrino induced meson production reactions, has been implemented for the first time in the SuSAv2-inelastic model to analyze the resonance region. The outcomes of these approaches are firstly benchmarked against (e, e') data on 12C....
The NEUT interaction generator is used in Super-Kamiokande, T2K and Hyper-Kamiokande to simulate neutrino interactions with between 100 MeV and a few TeV of energy. This talk will present the recent developments and perspective for NEUT.
The international GENIE Collaboration maintains and develops an extensive software suite to meet the simulation needs of the broad neutrino community. GENIE develops a universal event generator simulating neutrino interactions from MeV to PeV energy scales, and a global analysis of neutrino scattering data used for model characterization, tuning and uncertainty evaluations. In recent years,...
NuWro, a state-of-the-art Monte Carlo generator developed by theorists at the University of Wroclaw, simulates neutrino-nucleus interactions. This talk will demonstrate NuWro's capabilities, methodologies, and applications in simulating neutrino-nucleus interactions across a wide energy range, from a few hundred MeV to hundreds of GeV.
In my talk, I will discuss various interaction models...
Large liquid argon time projection chamber (LArTPC) neutrino detectors, such as those planned for the Deep Underground Neutrino Experiment (DUNE), show considerable promise as a platform for next-generation measurements of supernova neutrinos. Thanks to the neutron excess in 40Ar as well as the detailed tracking possible with LArTPCs, these detectors are expected to be uniquely capable of...
The Achilles is a novel neutrino event generator that takes inspiration from the tools developed by the LHC community. In this talk, I will discuss the current status of Achilles, with a focus on including resonance interactions, pion cascades, and the one-body-two-body interference terms. Additionally, I will discuss the near future plans for Achilles.
This talk presents a Monte Carlo simulation implemented with the GiBUU model tailored for neutrino experiments. Specifically, we focus on its implementation in generating events in a generic liquid argon time projection chamber and compare the results with those from other neutrino event generators, such as GENIE. The simulation produces realistic neutrino event samples, contributing to the...
The Deep Underground Neutrino Experiment (DUNE) is a next generation experiment aiming to answer a wide range of open questions in neutrino physics. Its broad program includes a long-baseline (LBL) neutrino oscillation analysis, whose goal is to measure neutrino oscillation parameters with unprecedented precision. The intense beam exposure, coupled with the size of the near and far detectors...
Neutrino event generators make use of intranuclear cascade models (INCs), to predict the kinematics of hadron production in neutrino-nucleus interactions. We perform a consistent comparison of different INCs, by using the same set of events as input to the NEUT, NuWro, Achilles and INCL INCs. The inputs correspond to calculations of the fully differential single-proton knockout cross section,...
Nuclear effects in neutrino-nucleus scattering are one of the main sources of uncertainty in the analysis of neutrino oscillation experiments. Due to the extended neutrino energy distribution, very different reaction mechanisms contribute to the cross section at the same time. Measurements of muon momentum in CC0$\pi$ events are very important for experiments like T2K, where most of the...
T2K is a long-baseline experiment for the measurement of neutrino oscillations. The neutrino flux and neutrino-nucleus cross-sections are measured by a suite of near detectors, including ND280, an off-axis multipurpose magnetised detector, WAGASCI, featuring a water-enriched target at a different off-axis angle, and INGRID an on-axis detector composed of sandwiched layers of iron and...
MINERvA is a dedicated neutrino-nucleus interaction experiment at Fermilab that took data from 2009-2019. MINERvA has made, and continues to make a wide range of measurements that inform the development of neutrino-nucleus interaction models that are used in current and future neutrino oscillation experiments. MINERvA has a wide range of different target nuclei ranging from hydrogen (in the...
The Scattering and Neutrino Detector at the LHC -- SND@LHC is a compact and stand-alone experiment to perform measurements with neutrinos produced at the LHC in a hitherto unexplored pseudo-rapidity region of $7.2 < \eta < 8.4$, complementary to all the other experiments at the LHC. The experiment is located 480 m downstream of IP1 in the unused TI18 tunnel. The detector is composed of a...
The NINJA experiment aims to measure neutrino-nucleus scattering using the J-PARC neutrino beam in the energy range of sub-GeV to a few-GeV. The NINJA detector comprises nuclear emulsion films interleaved with target materials, offering submicron spatial resolution and precise measurement of charged particles, particularly with the proton momentum threshold of 200 MeV/c.
We have collected...
Using the NOvA near Detector, the NOvA collaboration is able to measure a number of neutrino scattering processes.
The description of neutrino-nucleus interactions in the few-GeV regimes constitutes the dominant source of systematic uncertainty for current and future long-baseline neutrino oscillation experiments. In this work, based on the recent manuscript available at arXiv:2407.10962, neutrino-nucleus cross-section measurements of transverse kinematic imbalance from the T2K, MicroBooNE and MINERvA...
Tens of MeV neutrinos, such as those from stopped pion or core-collapse supernova sources, interact with target nuclei in detectors through either coherent elastic or inelastic scattering processes. These interactions provide valuable insights into various Standard Model and Beyond the Standard Model phenomena, with significant implications for nuclear physics, particle physics, and...
We study neutrino and antineutrino induced eta production from the free nucleon and nuclear targets. The hadronic current receives contribution from the background terms as well as from the nucleon and delta resonance excitations. We have considered only those nucleon/delta resonances which are present in the PDG having spin ≤ 3/2 and mass in the range < 2 GeV with significant branching ratio...
In this talk, we investigate the impact of nucleon-nucleon in-medium modifications on neutrino-nucleus cross section predictions using the GiBUU transport model. Historically studied in the context of heavy-ion collisions, the extent to which free nucleon-nucleon forces are modified in-medium remains undetermined by those data sets. We find that including an in-medium lowering of the NN cross...
Making high-precision measurements of neutrino oscillation parameters requires an unprecedented understanding of neutrino-nucleus scattering. To help fulfill this need, MicroBooNE has produced an extensive set of multi-differential charged-current muon neutrino cross-section measurements which probe both the leptonic and hadronic systems. This talk will present the first energy-dependent...

The detector is currently being commissioned and is collecting neutrino beam data. Located only 110 m from the neutrino production target, it will be exposed to a...
The Deep Underground Neutrino Experiment (DUNE) is a next-generation long-baseline neutrino oscillation experiment that will feature liquid argon time projection chamber technology for its near and far detectors. The liquid argon near detector (ND-LAr) is designed to handle the high intensity expected from the Long-Baseline Neutrino Facility (LBNF) beam using optically-separated TPC volumes, a...
Understanding neutrino-argon interactions with final-state pions or rare processes is vital for current and future argon-based neutrino experiments. In particular, interactions with pions will dominate the event rate observed at the forthcoming Deep Underground Neutrino Experiment and will be major backgrounds to appearance searches. Meanwhile, rare final states, such as those including Λ, K,...
The ICARUS experiment, utilizing Liquid Argon Time Projection Chamber (LAr TPC) technology, has been installed at Fermilab in Chicago, Illinois, following its initial operation in Italy and subsequent refurbishment at CERN. ICARUS has successfully been taking physics data at Fermilab since June 2022. While the experiment's primary objective is to function as the far detector of the...
We report on a global fit of neutral-current elastic (NCE) neutrino-scattering data and parity-violating electron-scattering (PVES) data with the goal of determining the strange quark contribution to the vector and axial form factors of the proton. Knowledge of the strangeness contribution to the axial form factor, $G_A^s(Q^2)$, at low $Q^2$ will reveal the strange quark contribution to the...
The choice of unfolding method for a cross-section measurement is tightly coupled to the model dependence of the efficiency correction and the overall impact of cross-section modeling uncertainties in the analysis. A key issue is the dimensionality used, as the kinematics of all outgoing particles in an event typically affects the reconstruction performance in a neutrino detector. OmniFold is...
Charged leptons produced by high-energy and ultrahigh-energy neutrinos have a substantial probability of emitting prompt internal bremsstrahlung $\nu_\ell + N \rightarrow \ell + X + \gamma$. This can have important consequences for neutrino detection. We discuss observable consequences at high- and ultrahigh-energy neutrino telescopes and LHC's Forward Physics Facility. Logarithmic...
The GiBUU´neutrino generator has been extended to also cover the neutrino fluxes encountered at the FASER experiment at CERN. Predictions for final state energy distributions and multiplicities are made. Particular emphasis is placed on a discussion of the extraction of formation times and interaction rates of newly formed hadrons.
