The NEUT neutrino interaction simulation program library

Abstract

is a neutrino–nucleus interaction simulation program library. It can be used to simulate interactions for neutrinos with between 100 MeV and a few TeV of energy. is also capable of simulating hadron interactions within a nucleus and is used to model nucleon decay and hadron–nucleus interactions for particle propagation in detector simulations. This article describes the range of interactions modelled and how each is implemented.

Comparisons and challenges of modern neutrino-scattering experiments (TENSIONS 2019 report)

“…Understanding interaction-model dependence in neutrino-oscillation experiments is a topic of particular interest [9,19,20]. The generators used in existing accelerator experiments, GENIE [15] and NEUT [17,21], have been developed primarily within the experimental community, drawing on published theoretical work or direct collaborations with theorists to develop models. While in many cases models are similar with respect to the underlying theory, differences in implementation and parameter choices can lead to important differences in generator predictions; this is evident in the comparisons shown in later sections.…”

First Measurement of Energy-Dependent Inclusive Muon Neutrino Charged-Current Cross Sections on Argon with the MicroBooNE Detector

“…3a), where the bin-center is calculated as the flux-weighted average neutrino energy. Besides the nominal cross-section model used in the "MicroBooNE MC" [18], predictions from GENIE v3.0.6 [19,52], NuWro 19.02.01 [53], NEUT 5.4.0.1 [54], and GiBUU 2019.08 [55] after applying the Wiener filter are quantitatively compared with the measurement through calculating χ 2 /ndf with the uncertainty covariance matrix obtained from the unfolding procedure. Note that these comparisons only incorporate the central predictions from various generators without their theoretical uncertainties, which are particularly important in constructing predictions in analysis.…”

Neural-network-driven proton decay sensitivity in the $p\rightarrow \barν K^{+}$ channel using large liquid argon time projection chambers

“…table 4. The final state interaction rate of K + inside the remnant nucleus has been cross-checked with NEUT, a generator toolkit developed in the context of the T2K experiment [47]. NEUT yields a total interaction rate of 35 % with a model combination similar to the alternative GENIE tune, confirming the interaction rate of 32 % obtained with GENIE.…”
