Ambiguities of neutrino(antineutrino) scattering on the nucleon due to the uncertainties of relevant strangeness form factors

TL;DR

This paper investigates how uncertainties in strangeness form factors affect neutrino and antineutrino scattering on nucleons, using combined experimental data to analyze observable ambiguities in the quasi-elastic energy range.

Contribution

It provides a comprehensive analysis of the impact of strangeness form factor uncertainties on neutrino scattering observables, incorporating recent combined experimental data.

Findings

Uncertainties in strangeness form factors lead to significant ambiguities in scattering observables.

Combined parity-violating electron and neutrino scattering data help constrain strangeness contributions.

Implications for neutrino-nucleus scattering applications are discussed.

Abstract

Strange quark contributions to neutrino(antineutrino) scattering are investigated on the nucleon level in the quasi-elastic region. The incident energy range between 500 MeV and 1.0 GeV is used for the scattering. All of the physical observable by the scattering are investigated within available experimental and theoretical results for the strangeness form factors of the nucleon. In specific, a newly combined data of parity violating electron scattering and neutrino scattering is exploited. Feasible quantities to be explored for the strangeness contents are discussed for the application to neutrino-nucleus scattering.
