“…A simultaneous fit to two theoretical model parameters obtained the values M A = 1.10 +0. 13 −0.15 GeV and g s A = −0.4 +0.5 −0.3 , consistent with the older evaluations based on the neutrino-deuteron scattering data. In the analysis of the NCE data the effective transverse enhancement (TE) model [228] is used, because to date this is the only NC np-nh model available in NuWro.…”

The treatment of nuclear effects in neutrino-nucleus interactions is one of the main sources of systematic uncertainty for the analysis and interpretation of data of neutrino oscillation experiments. Neutrinos interact with nuclei via charged or neutral currents and both cases must be studied to obtain a complete information. We give an overview of the theoretical work that has been done to describe nuclear effects in neutral-current neutrinonucleus scattering in the kinematic region ranging between beam energies of a few hundreds MeV to a few GeV, which is typical of most ongoing and future accelerator-based neutrino experiments, and where quasielastic scattering is the main interaction mechanism. We review the current status and challenges of the theoretical models, the role and relevance of the contributions of different nuclear effects, and the present status of the comparison between the numerical predictions of the models as well as the available experimental data. We discuss also the sensitivity to the strange form factors of the nucleon and the methods and observables that can allow one to obtain evidence for a possible strange quark contribution from measurements of neutrino and antineutrino-nucleus scattering.

“…The combination of these models would allow for a consistent picture of an axial mass close to 1.00 GeV/c 2 , with a suppressed cross section at low-Q 2 and larger cross section at higher-Q 2 relative to a simple RFG model. Comprehensive reviews of available CCQE cross section models can be found in References [3,[20][21][22].…”

“…Although alternative nuclear models modify the cross section as a function of the outgoing lepton kinematics significantly, they do not change the total CCQE cross section significantly as a function of neutrino energy [21]. Additional nuclear effects are also likely to be required to explain the current global dataset.…”

The MiniBooNE large axial mass anomaly has prompted a great deal of theoretical work on sophisticated Charged Current Quasi-Elastic (CCQE) neutrino interaction models in recent years. As the dominant interaction mode at T2K energies, and the signal process in oscillation analyses, it is important for the T2K experiment to include realistic CCQE cross section uncertainties in T2K analyses. To this end, T2K's Neutrino Interaction Working Group has implemented a number of recent models in NEUT, T2K's primary neutrino interaction event generator. In this paper, we give an overview of the models implemented, and present fits to published νµ and νµ CCQE cross section measurements from the MiniBooNE and MINERνA experiments. The results of the fits are used to select a default cross section model for future T2K analyses, and to constrain the cross section uncertainties of the model. We find a model consisting of a modified relativistic Fermi gas model and multinucleon interactions most consistently describes the available data.

“…The nuissyst application can be used to study the effects of cross-section systematics on userspecified distributions in a number of ways, provided that the generators have reweighting libraries enabled 5 . It can step through a range of values for a reweightable parameter 6 and validate reweighting implementations.…”

NUISANCE: a neutrino cross-section generator tuning and comparison framework

Prepared for submission to JINST NUISANCE: a neutrino cross-section generator tuning and comparison frameworkl A a L * 1 Abstract: NUISANCE is an open source C++ framework which facilitates detailed studies of neutrino interaction cross-section models implemented in Monte Carlo neutrino event generators. It provides a host of automated methods to perform comparisons of multiple generators to published cross-section measurements and each other. External reweighting libraries are used to allow the end-user to evaluate the impact of model parameters variations in the generators with data, or to tune the generator predictions to arbitrary dataset combinations. The design is modular and focusses on ease-of-use to allow new datasets and more generators to be added without requiring detailed understanding of the entire NUISANCE package. We discuss the motivation for the NUISANCE framework and suggested usage cases, alongside a description of its core structure.
