“…Low W (W < Wcut) multipion production is modeled based on the DIS contribution. At higher values of W GENIE relies on the Bodek-Yang DIS [35] cross section and its own AGKY hadronization model [36]. A hadronic formation zone effect is also implemented.…”

“…Here, two data sets from the Fermilab bubble chamber and BEBC agree in ν µ − n interactions (both deuterium targets) but not in ν µ − p data (hydrogen and deuterium target), suggesting the conflict of data we see in Fig. 2 is due to nuclears effect in deuterium [4,5,16,23]. Despite with the conflict of data set, the HERMES parameterization in general increases the averaged charged hadron multiplicity, which improves the agreement with averaged charged hadron multiplicity data from neutrino bubble chamber experiments.…”

Next generation neutrino oscillation experiments utilize details of hadronic final states to improve the precision of neutrino interaction measurements. The hadronic system was often neglected or poorly modelled in the past, but they have significant effects on high precision neutrino oscillation and cross-section measurements. Among the physics of hadronic systems in neutrino interactions, the hadronization model controls multiplicities and kinematics of final state hadrons from the primary interaction vertex. For relatively high invariant mass events, many neutrino experiments rely on the PYTHIA program. Here, we show a possible improvement of this process in neutrino event generators, by utilizing expertise from the HERMES experiment. Finally, we estimate the impact on the systematics of hadronization models for neutrino mass hierarchy analysis using atmospheric neutrinos such as the PINGU experiment.

“…These processes are very difficult to model. GENIE [8] uses scaling methods [26] to extend PYTHIA [27,28] to this region. Nonetheless, there are several remaining discrepancies between experimental data and theory, and work is ongoing to improve the performance of both GENIE and other neutrino interaction simulation tools (see e.g.…”

Studying atmospheric neutrino oscillations in the few-GeV range with a multimegaton detector promises to determine the neutrino mass hierarchy. This is the main science goal pursued by the future KM3NeT/ORCA water Cherenkov detector in the Mediterranean Sea. In this paper, the processes that limit the obtainable resolution in both energy and direction in charged-current neutrino events in the ORCA detector are investigated. These processes include the composition of the hadronic fragmentation products, the subsequent particle propagation and the photon-sampling fraction of the detector. GEANT simulations of neutrino interactions in seawater produced by GENIE are used to study the effects in the 1-20 GeV range. It is found that fluctuations in the hadronic cascade in conjunction with the variation of the inelasticity y are most detrimental to the resolutions. The effect of limited photon sampling in the detector is of significantly less importance. These results will therefore also be applicable to similar detectors/media, such as those in ice.
