The main source of systematic uncertainty on neutrino cross section measurements at the GeV scale originates from 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 Light Dark Matter eXperiment (LDMX) is a proposed small-scale accelerator experiment designed to search for dark matter using missing energy and momentum techniques from multi-GeV electro-nuclear interactions. In order to detect and veto against energy losses from standard electro-nuclear scattering processes, the detector design features charged particle tracking and hermetic calorimetry...
The ability of current and next generation accelerator-based neutrino-oscillation measurements to
reach their desired sensitivity requires a detailed understanding of neutrino-nucleus interactions.
These include precise knowledge of the relevant cross sections and of our ability to reconstruct
the incident neutrino energy from the measured final state particles. Incomplete understanding...
State-of-the-art predictions of accelerator-based neutrino fluxes have uncertainties ranging from 5-15%, dominated by hadron production uncertainties. The EMPHATIC Collaboration has proposed a unique, compact spectrometer to measure hadron-scattering and hadron-production cross sections that are needed to reduce neutrino flux uncertainties for current and future neutrino experiments to the...
We report on a phenomenological analysis of all available electron scattering data on carbon (about 8000 differential cross section measurements) and oxygen at all values of q. The QE cross section is modeled within the framework of the superscaling model (including Pauli blocking). In addition to the expected enhancement of the transverse QE response function we find that at low values of...
MicroBooNE data of charged current inclusive neutrino cross sections on argon as a function of different kinematical variables have recently appeared. We compare these data to our theoretical calculations after a brief review of our RPA model and of its successful predictions for the MiniBooNE and T2K cross sections on carbon. Overall we find an agreement with MicroBooNE data in spite of a...
The description of final-state interactions (FSI) in the large phase space probed in neutrino experiments poses a great challenge. In neutrino experiments, which operate under semi-inclusive conditions, cascade models are commonly used for this task, while under exclusive conditions FSI can be treated with relativistic optical potentials (ROP). We formulate conditions under which the ROP...
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 (flux), 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...
We present a global analysis of neutrino DIS cross-sections in the framework of nuclear parton distribution functions (PDFs). In our previous analysis (circa 2011), we concluded that some neutrino DIS data, particularly from the NuTeV experiment, were incompatible with the remaining nuclear scattering data. We have now performed a follow-up analysis that improves the previous study in many...

Simulation plays a critical role in neutrino experiments. But for a variety of reasons no simulation is perfect, and experiments must confront discrepancies between simulated predictions and their own measurements and observations. This inevitably leads to the need to tune the simulation in order to obtain robust and reasonable systematic uncertainties in analyses. In this talk I give an...
