“…In particular, the Fermi motion of inside nucleons turns out to be important [14]. For example, our recent calculations using the distorted-wave Born approximation (DWBA) [12] show the importance of the nuclear effects and Coulomb distortion.…”

“…Meanwhile, the MiniBooNE data addressed the fact that the experimental data are governed by the value of axial mass M A = 1.39 ∼ 1.35 GeV which is larger than the standard value M A = 1.03 GeV and the strange axial form factor, i.e. g s A = 0.08 at Q 2 = 0, although there are many issues that remain unresolved [12]. One of these involves the in-medium effect due to the embedded nucleon in a nucleus.…”

“…However, there are still several points to be discussed for further understanding the differences between theoretical results and the data as follows [12]: The first is multi-particle, multi-hole contributions beyond 1p-1h, which are found to be important for the CC reaction in the QE region [15]. The second is the ambiguity regarding a change in axial mass and strangeness content.…”

“…The last possibility is the explicit consideration of the in-medium effect by the modification of form factors embedded in the weak current [18,19]. Our recent calculations [18,19] by the distorted wave Born approximation (DWBA) and the quasi-particle random phase approximation (QRPA) [20] showed that differential cross sections for the neutrino-induced reaction in 12 C by an E ν of less than 100 MeV may be altered by about 20 ∼ 30 % by the in-medium effect. In these calculations, we exploited the density-dependent weak form factors estimated in the quark-meson-coupling model (QMC) [21].…”

Abstract. We reviewed present status regarding experimental data and theoretical approaches for neutrino-induced reactions and neutrino scattering. With a short introduction of relevant data, our recent calculations by distorted-wave Born approximation for quasielastic region are presented for MiniBooNE data. For much higher energy neutrino data, such as NOMAD data, elementary process approach was shown to be useful instead of using complicated nuclear models. But, in the low energy region, detailed nuclear structure model, such as QRPA and shell model, turn out to be inescapable to explain the reaction data. Finally, we discussed that one step-process in the reaction is comparable to the two-step process, which has been usually used in the neutrino-nucleosynthesis.

We investigated the in-medium effect by density-dependent axial and weak-vector form factors on muon-neutrino ( ) and anti-muon-neutrino scattering in the quasi-elastic (QE) region from nucleons (N*) bound in a nucleus or immersed in a nuclear medium via neutral current (NC) and charged current (CC). For the density-dependent form factors, we exploited a quark–meson-coupling (QMC) model. We found that the scattering cross sections via NC in the QE region usually decrease with an increased medium density, while those using CC were increased. However, their rate of change was sensitive to the four-momentum transfer given to a bound nucleon through scattering. We compared these results obtained by the elementary process corrected by the in-medium effect to the BNL and MiniBooNE data, which measured scattering cross sections per nucleon through – 12C scattering in 12C composite targets. The incident energy range was 550 3000 MeV. We increased the energy up to 100 GeV to compare our results to the NOMAD experimental data. In order to study the density effects on a nucleon embedded in 12C, we exploited the QMC form factors evaluated at , where the normal density . The strangeness contributions in NC scattering are also incorporated into the form factors for comparison with experimental data. Our numerical results show that most of the experimental data can be explained in a satisfactory manner by the density-dependent elementary process, but there are some remaining deviations resulting from the nuclear structure, particularly in the low and high momentum-transfer regions.
