“…Therefore, ratios of cross sections have been proposed as alternative and useful tools to search for strangeness effects. The ratio of proton-to-neutron cross sections was proposed and discussed in [89][90][91][92][93][94][95]. This ratio is very sensitive to strange-quark effects because the axial strangeness s interferes with the isovector contribution to the axial form factor g A ≈ 1.27 with one sign in the numerator and with the opposite sign in the denominator.…”

We evaluate semi-inclusive neutral-current quasielastic differential neutrino and antineutrino cross sections within the framework of the relativistic impulse approximation. The results of the relativistic mean-field and of the relativistic Green's function models are compared. The sensitivity to the strange-quark content of the nucleon form factor is also discussed. The results of the models are compared with the MiniBooNE experimental data for neutrino scattering. Numerical predictions for flux-averaged antineutrino scattering cross sections are also presented.

“…Figure 4 displays R p/n for both neutrino and antineutrino NC interactions on 12 C. The coinciding curves representing the results with and without the effect of FSI, illustrate the negligible influence of final-state interactions on these cross-section ratios [35,36]. This figure, as well as the left panel of Fig.…”

“…Several recent theoretical studies of neutrino-nucleus scattering at intermediate energies [33][34][35][36] highlighted particular aspects of the strangeness glimpses that can be caught in quasielastic neutrino-scattering experiments. In this article, we aim at providing a more systematic overview of the sensitivity of various neutrino cross-section ratios to the nucleon's strange quark content.…”

We present a systematic study of the sensitivity of quasielastic neutrino-nucleus cross sections at intermediate energies to the strange quark sea of the nucleon. To this end, we investigate the impact of the weak strangeness form factors on the ratio of proton-to-neutron knockout, the ratio of neutral-to-charged current cross sections, on the Paschos-Wolfenstein relation, and on the longitudinal helicity asymmetry. The influence of axial as well as vector strangeness effects is discussed. For the latter, we introduce strangeness parameters from various hadron models and from a recent fit to data from parity-violating electron scattering. In our model, the nuclear target is described in terms of a relativistic mean-field approach. The effects of final-state interactions on the outgoing nucleon are quantified within a relativistic multiple-scattering Glauber approach. Our results are illustrated with cross sections for the scattering of 1-GeV neutrinos and antineutrinos off a 12 C target. Folding with a proposed FINeSSE (anti-)neutrino energy distribution has no qualitative influence on the overall sensitivity of the cross-section ratios to strangeness mechanisms. We show that vector strangeness effects are large and strongly Q 2 dependent.

“…Electron-nucleus parity violation (PV), as well as NC neutrino scattering in free nucleons have put stringent bounds on the strange form factors, and further electron PV experiments will make uncertainties due to the strangeness content of the nucleon even smaller. It is however worth mention that further experimental measurement of neutron-proton relative yields or asymmetries, or the so-called Wolfestein parameter, in neutrino experiments, will be very useful in settling down the contribution from strange form factors [19,20,21].…”

Abstract. A review of quasielastic neutrino-nucleus scattering will be presented, with emphasis on bringing together the knowledge (and language) of neutrino physics, electron scattering, and nuclear structure communities. Assumptions commonly made which simplify the theoretical calculations will be examined. Finally, an attempt will be made to identify places where improvement from either theoretical or experimental sides would be more significant.
