Superscaling predictions for neutrino-induced charged-current charged pion production at MiniBooNE

TL;DR

This paper applies the superscaling approximation (SuSA) to predict neutrino-induced charged-current charged pion production at MiniBooNE, showing good agreement with experimental flux-averaged cross sections but differing in energy dependence.

Contribution

The study extends the SuSA model to charged pion production in the -resonance region under MiniBooNE conditions, providing new predictions and comparisons with data.

Findings

SuSA accurately predicts flux-averaged cross sections.

Predicted energy dependence differs from experimental analysis.

Good agreement with MiniBooNE data on certain observables.

Abstract

Superscaling approximation (SuSA) predictions to neutrino-induced charged-current charged pion production in the \Delta-resonance region are explored under MiniBooNE experimental conditions. The results obtained within SuSA for the flux-averaged double-differential cross sections of the \pi+ production for the \nu_\mu+CH_2 reaction as a function of the muon kinetic energy and of the scattering angle, the cross sections averaged over the angle, the total cross section for the \pi+ production, as well as CC1\pi+ to CCQE cross section ratio are compared with the corresponding MiniBooNE experimental data. The SuSA predictions are in good agreement with data on neutrino flux average cross-sections, but a somewhat different dependence on the neutrino energy is predicted than the one resulting from the experimental analysis.
