The Short-Baseline Near Detector (SBND) is a 112-ton scale Liquid Argon Time Projection Chamber (LArTPC) neutrino detector positioned in the Booster Neutrino Beam at Fermilab, as part of the Short-Baseline Neutrino (SBN) program. The detector is currently collecting neutrino beam data. Located only 110 m from the neutrino production target, SBND is exposed to a very high flux of neutrinos and...
MicroBooNE is a Liquid Argon Time Projection Chamber, able to image neutrino interactions with excellent spatial and timing resolution, enabling the identification of complex final states resulting from neutrino-nucleus interactions. As a result, MicroBooNE has produced a variety of neutrino cross-section measurements on argon, spanning almost four orders of magnitude and across all major...
The Deep Underground Neutrino Experiment (DUNE) is a cutting-edge long-baseline experiment under construction in the United States. DUNE will use a far detector (FD) and a near detector (ND) to sample a high-intensity neutrino beam produced at Fermilab. This experiment aims to conduct precise studies of neutrino oscillations, establish the ordering of neutrino masses, and investigate potential...
The ICARUS experiment, utilising 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 Short...
We present the implementation of the MartiniโEricsonโChanfrayโMarteau RPA-based (anti)neutrino cross section model in the GENIE neutrino event generator. The implementation includes both the quasielastic (1p1h) and multinucleon (npnh) interaction channels. The presentation will begin with an overview of the theoretical foundations of the model. Validation steps are then discussed, along with...
Pion production is one of the critical interaction systematic uncertainties in neutrino oscillation measurements. Recent GiBUU development has introduced many improvements in the treatment of pion production, including the $2\pi$ background in neutrino interactions. We present a comprehensive study of charge current neutrino-induced pion production with the GiBUU model by examining the...
Reliable theoretical modeling of neutrino-nucleus interactions is an essential requirement for current and next-generation neutrino-oscillation experiments, such as MicroBooNE and DUNE, which use argon as the target material. In this talk, I will present recent advancements in the treatment of the quasi-elastic (QE) channel in the NuWro Monte Carlo event generator. We implement the...
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 MeV's to hundreds of GeV. Lastly, I will present the highlights of NuWro v25.03 which was...
The SND@LHC experiment was designed to perform measurements with neutrinos produced at the LHC within the unexplored pseudo-rapidity range of 7.2 < ๐ < 8.6. Located 480 m downstream of IP1 in the unused TI18 tunnel, this compact and stand-alone experiment employs a hybrid detector system consisting of 800 kg of tungsten plates interleaved with emulsion and electronic trackers, complemented by...
The ForwArd Search ExpeRiment (FASER) is designed to search for particles produced in the far-forward region of pp collisions at the LHC at CERN. Its primary goals are to detect high-energy neutrinos and light, feebly interacting new particles predicted by extensions of the Standard Model. Since its inception in 2022, FASER has collected close to 200/fb of data during LHC Run 3, leading to...
The poor knowledge of neutrino cross sections at the GeV scale is projected to be responsible for some of the leading sources of uncertainty in next-generation oscillation experiments. Building on the ideas and R&D from ENUBET and NuTAG, we present a proposal for the nuSCOPE experiment (see arXiv:2503.21589). nuSCOPE is a high-precision, short-baseline neutrino experiment at CERN that employs...
We present a new global analysis of nuclear PDFs in the nCTEQ approach. Building on a modern proton baseline without nuclear data, we combine and update previous separate analyses that focused on JLab neutral-current DIS, neutrino DIS and dimuon production, and the currently available LHC data, in particular on W/Z and heavy quark production. For the latter, we not only employ a data-driven...
The T2K experiment's primary off-axis near detector, ND280, has the essential role of constraining the main systematic uncertainties that affect neutrino oscillation measurements. Among the leading sources of these uncertainties are neutrino-nucleon interaction cross sections, which must be more precisely understood to fully exploit the potential of current and future long-baseline neutrino...
The T2K experiment has operated for over a decade using the on-axis near detector INGRID and ND280 as the primary near detector for oscillation and neutrino interaction physics at 2.5 degrees off-axis, both located at JPARC. Recent upgrades to T2K include an increased power at JPARC's neutrino beamline, detector upgrades to ND280, and the installation of a second near detector,...
We present preliminary measurements on $\nu_\mu$ charged-current interactions on water, obtained from the first physics run of the NINJA experiment. The interactions were recorded using nuclear emulsion detectors with a 75 kg water target exposed to a J-PARC $\nu_\mu$ beam of mean energy 0.86 GeV and a total exposure of $4.8\times10^{20}$ protons on target. The sub-micrometer spatial...
Understanding both neutrino and antineutrino interactions in the few-GeV regime is necessary for precision measurements of neutrino oscillations. In particular, it is crucial to study the nuclear effects that can alter final-state topology and kinematics, potentially biasing neutrino energy reconstruction. MINERvA is a high-statistics cross-section experiment designed to study such nuclear...
Liquid argon serves as detector material in several present and future accelerator-based neutrino experiments, such as MicroBooNE, SBND, ICARUS [1] and DUNE [2].
Therefor, precise information about the structure of the target nucleusโthat is, the binding energies and momentum distributions of the nucleonsโis crucial for accurate modeling of neutrinoโnucleus cross sections. This is...
We compute the contribution of meson-exchange currents (MEC) to the one-particle
emission transverse response of nuclear matter, including short-range correlations (SRC)
within the independent pair approximation. Our results show a significant enhancement
of the transverse response in electron scattering, in contrast to independent-particle
models that neglect SRC [1]. SRC are incorporated...
We report on global extractions of the $\rm^{12}C$, $\rm^{40}Ca$ and $\rm^{56}Fe$ longitudinal (${\cal R}_L$) and transverse (${\cal R}_T$) nuclear electromagnetic response functions from an analysis of all available electron scattering and photoprodution data on these nuclei. The response functions are extracted for energy transfer $\nu$, spanning the nuclear excitation,...
Single-pion production provides an important contribution to the total neutrino-nucleus interaction cross section in neutrino oscillation experiments. This contribution improves the Ghent Hybrid model in the delta-resonance region. The philosophy of this work is to incorporate as much physics constraints as possible while keeping the amount of fitted parameters as low as possible. The model is...
