“…This assumption is supported by the observation that for nuclei with mass number A 4, the momentum distribution (per nucleon) is largely independent of A for momentum higher than ∼300 MeV [48]. In the LDA scheme, the shell structure of the nucleus, deduced from experimental (e, e ) data [49,50], can consistently be combined with the correlation contribution obtained from theoretical calculations for uniform nuclear matter at different densities [33,51].

Background. Good understanding of the cross sections for (anti)neutrino scattering off nuclear targets in the few-GeV energy region is a prerequisite for the correct interpretation of results of ongoing and planned oscillation experiments. Purpose. Clarify a possible source of disagreement between recent measurements of the cross sections on carbon. Method. Nuclear effects in (anti)neutrino scattering off carbon nucleus are described using the spectral function approach. The effect of two-and multinucleon final states is accounted for by applying an effective value of the axial mass, fixed to 1.23 GeV. Neutral-current elastic (NCE) and charged-current quasielastic (CCQE) processes are treated on equal footing. Results. The differential and total cross sections for the energy ranging from a few hundreds of MeV to 100 GeV are obtained and compared to the available data from the BNL E734, MiniBooNE, and NOMAD experiments. Conclusions. Nuclear effects in NCE and CCQE scattering seem to be very similar. Within the spectral function approach, the axial mass from the shape analysis of the MiniBooNE data is in good agreement with the results reported by the BNL E734 and NOMAD Collaborations. However, the combined analysis of the NCE and CCQE data does not seem to support the contribution of multinucleon final states being large enough to explain the normalization of the MiniBooNE-reported cross sections.

Electroweak pion production on nuclei within the extended factorization scheme

et al. 2019

View full text Add to dashboard Cite

We have applied the extended factorization scheme to investigate the electroweak pion production on nuclei. The ANL-Osaka model, which was obtained by analyzing the data of πN , γN , N (e, e π) and N (ν, µ π) reactions up to invariant mass W = 2 GeV, is used to generate the matrix elements of current operators relevant to pion-production off the nucleon. Medium effects on the ∆ (1232) component of meson-exchange current are included by using a ∆-nucleus potential determined from the previous ∆-hole model studies of pion-nucleus reactions. Nuclear correlations in the initial target state and in the spectator system(s) are modeled using realistic hole spectral functions. As a first step, we show that the data of 12 C(e, e ) up to the ∆ (1232) region can be described reasonably well. The interplay between the pion production and two-body meson-exchange mechanisms is shown to be essential in improving the agreement with the data in the "dip" region, between the quasielastic and the ∆ (1232) peaks. Predictions for 12 C(ν, µ π) have also been made. They can be used to estimate pion-emission rates in neutrino-nucleus cross section, which constitutes an important systematic uncertainty to the reconstructed neutrino energy. With further improvements of the Metropolis Monte-Carlo techniques to account for final states comprised of more than two particles, our approach can be employed up to W = 2 GeV, where two-pion production and higher mass nucleon resonances must be included for analyzing the data from accelerator-based neutrinooscillation experiments.

Background:The recent Jefferson Laboratory data for the nuclear transparency in ρ 0 electroproduction have the potential to settle the scale for the onset of color transparency (CT) in vector meson production. Purpose: To compare the data to calculations in a relativistic and quantum-mechanical Glauber model and to investigate whether they are in accordance with results including color transparency given that the computation of ρ-nucleus attenuations is subject to some uncertainties. Method: We compute the nuclear transparencies in a multiple-scattering Glauber model and account for effects stemming from color transparency, from ρ-meson decay, and from short-range correlations (SRC) in the final-state interactions (FSI). Results:The robustness of the model is tested by comparing the mass dependence and the hard-scale dependence of the A(e, e p) nuclear transparencies with the data. The hard-scale dependence of the (e, e ρ 0 ) nuclear transparencies for 12 C and 56 Fe are only moderately affected by SRC and by ρ 0 decay. Conclusions:The RMSGA calculations confirm the onset of CT at four-momentum transfers of a few (GeV/c) 2 in ρ meson electroproduction data. A more precise determination of the scale for the onset of CT is hampered by the lack of precise input in the FSI and ρ-meson decay calculations.
