“…Details of the RGF model can be found, for instance, in [85] and [86]. The results of the RMF and RGF models have been widely compared in [63] for inclusive QE electron scattering, in [55] and [87] for CCQE, and in [61] for NCQE neutrino scattering. RGF calculations presented in this work were carried out with the recent democratic optical potential of [88] (RGF-DEM).…”

Neutral current quasielastic (anti)neutrino scattering cross sections on a 12 C target are analyzed using a realistic spectral function S(p,E) that gives a scaling function in accordance with the (e,e ) scattering data. The spectral function accounts for the nucleon-nucleon (NN) correlations by using natural orbitals from the Jastrow correlation method and has a realistic energy dependence. The standard value of the axial mass M A = 1.032 GeV is used in all calculations. The effect of the final-state interaction on the spectral and scaling functions, as well as on the cross sections, is accounted for. A comparison of the calculations with the empirical data of the MiniBooNE and BNL experiments is performed. Our results are analyzed in comparison with those when NN correlations are not included and, also, with results from other theoretical approaches, such as the relativistic Fermi gas, the relativistic mean field, and the relativistic Green's function, as well as with the SuperScaling Approach based on the analysis of quasielastic electron scattering.

“…Because of the analyticity properties of the OP, the RGF model fulfills the Coulomb sum rule [63,92,97]. More details about the RGF model can be found in [48,[63][64][65][66][67][92][93][94][95][96] The RGF results can give a satisfactory description of experimental (e, e ′ ) cross sections in the QE region [48,66]. In particular, the RGF provides a significant asymmetry in the scaling function, in agreement with the general behavior of electron scattering data that present a significant tail extended to large values of the transferred energy [98].…”

Elastic and quasi-elastic electron scattering on theN=14, 20, and 28 isotonic chains

We present theoretical predictions for electron scattering on the N = 14, 20, and 28 isotonic chains from proton-deficient to proton-rich nuclei. The calculations are performed within the framework of the distorted-wave Born approximation and the proton and neutron density distributions are evaluated adopting a Relativistic Hartree-Bogoliubov (RHB) approach with a density dependent meson-exchange interaction. We present results for the elastic and quasi-elastic cross sections and for the parity-violating asymmetry parameter. Owing to the correlations between the evolution of the electric charge form factors along each chain with the underlying proton shell structure of the isotones, elastic electron scattering experiments on isotones can provide useful informations about the occupation and filling of the single-particle levels of protons.

Abstract.After a short review of the recent developments in studies of neutrino-nucleus interactions, the predictions for double-differential and integrated charged current-induced quasielastic cross sections are presented within two different relativistic approaches: one is the so-called SuSA method, based on the superscaling behavior exhibited by electron scattering data; the other is a microscopic model based on relativistic mean field theory, and incorporating final-state interactions. The role played by the meson-exchange currents in the two-particle two-hole sector is explored and the results are compared with the recent MiniBooNE data. IntroductionThe analysis and interpretation of ongoing and future neutrino oscillation experiments strongly rely on the nuclear modeling for describing the interaction of neutrinos and anti-neutrinos with the detector. Moreover, neutrino-nucleus scattering has recently become a matter of debate in connection with the possibility of extracting information on the nucleon axial mass. Specifically, the data on muon neutrino charged-current quasielastic (CCQE) cross sections obtained by the MiniBooNE collaboration [1] are substantially underestimated by the Relativistic Fermi Gas (RFG) prediction. This has been ascribed either to effects in the elementary neutrino-nucleon interaction, or to nuclear effects. The most poorly known ingredient of the single nucleon cross section is the cutoff parameter M A employed in the dipole prescription for the axial form factor of the nucleon, which can be extracted from ν and ν scattering off hydrogen and deuterium and from charged pion electroproduction. If M A is kept as a free parameter in the RFG calculation, a best fit of the MiniBooNE data yields a value of the order of 1.35 GeV/c 2 , much larger than the average value M A ≃ 1.026 ± 0.021 GeV/c 2 extracted from the (anti)neutrino world data [2]. This should be taken more as an indication of incompleteness of the theoretical description of the data based upon the RFG, rather than as a true indication for a larger axial mass. Indeed it is well-known from comparisons with electron scattering data that the RFG model is too crude to account for the nuclear dynamics. Hence it is crucial to explore more sophisticated nuclear models before drawing conclusions on the value of M A .Several calculations have been recently performed and applied to neutrino reactions. These include, besides the approach that will be presented here, models based on nuclear spectral functions [3,4,5,6,7,8,9, 10], relativistic independent particle models [11,12,13], relativistic Green function approaches [14,15,16,17,18], models including NN correlations [19,20,21],
