“…Meucci et al [22,23] apply a relativistic Green's function approach to both inclusive and exclusive processes. They achieve an impressive description for the data on both the longitudinal and transverse response functions in the QE region.…”

“…Also this approach describes inclusive electron scattering data with impressive agreement. A relativistic Green's function approach was applied by Meucci et al [22,23] to inclusive electron as well as to inclusive neutrino nucleus reactions. Butkevich et al [24,25] addresses both neutrino and electron scattering with special emphasis on the impact of different impulse approximation (IA) schemes: plane wave IA (PWIA) and relativistic distorted wave IA (RD-WIA).…”

Electron- and neutrino-nucleus scattering from the quasielastic to the resonance region

et al. 2009

We present a model for electron-and neutrino-scattering off nucleons and nuclei focussing on the quasielastic and resonance region. The lepton-nucleon reaction is described within a relativistic formalism that includes, besides quasielastic scattering, the excitation of 13 N * and ∆ resonances and a non-resonant single-pion background. Recent electron-scattering data is used for the state-ofthe-art parametrizations of the vector form factors; the axial couplings are determined via PCAC and, in the case of the ∆ resonance, the axial form factor is refitted using neutrino-scattering data. Scattering off nuclei is treated within the Giessen Boltzmann-Uehling-Uhlenbeck (GiBUU) framework that takes into account various nuclear effects: the local density approximation for the nuclear ground state; mean-field potentials and in-medium spectral functions. Results for inclusive scattering off Oxygen are presented and, in the case of electron-induced reactions, compared to experimental data and other models.

“…The adequacy of the potential to be employed for inclusive scattering has been investigated in several works [32][33][34][35]. Besides the RMF, approaches where one uses only the real part of the optical potential [29], or where the full optical potential is employed but a formal summation based on Green function formalism over all possible channels that contribute to the inclusive scattering is done [32,34,35], have been used to describe lepton-nucleus scattering under inclusive conditions.…”

The comparison of results from these approaches show that they differ by a few percent and in general they compare equally well to existing electron scattering data.…”

Final-state interactions in the superscaling analysis of neutral-current quasielastic neutrino scattering

et al. 2008

Effects of strong final-state interactions in the superscaling properties of neutral-current quasielastic neutrino cross sections are investigated by using the relativistic impulse approximation as guidance. First-and second-kind scaling are analyzed for neutrino beam energies ranging from 1 to 2 GeV for the cases of 12 C, 16 O, and 40 Ca. Different detection angles of the outgoing nucleon are considered to sample various nucleon energy regimes. Scaling of the second kind is shown to be very robust. The validity of first-kind scaling is found to be linked to the kinematics of the process. Superscaling still prevails even in the presence of very strong final-state interactions, provided that some kinematical restrains are kept, and the conditions under which superscaling can be applied to predict neutral-current quasielastic neutrino scattering are determined.

“…Ignoring them would lead to an underestimation of the inclusive cross section [27,32,33]. Multiple nucleon knockout effects have been treated in detail within the context of the Green function method [34][35][36][37]. A simple way of obtaining the inclusive strength within the RIA is to use purely real potentials.…”

The phenomenon of superscaling for quasielastic lepton induced reactions at energies of a few GeV is investigated within the framework of the relativistic impulse approximation. A global analysis of quasielastic inclusive electron and charged-current neutrino scattering reactions on nuclei is presented. Scaling and superscaling properties are shown to emerge from both types of processes. The crucial role played by final state interactions is evaluated by using different approaches. The asymmetric shape presented by the experimental scaling function, with a long tail in the region of positive values of the scaling variable, is reproduced when the interaction in the final state between the knockout nucleon and the residual nucleus is described within the relativistic mean field approach. The impact of gauge ambiguities and off-shell effects in the scaling function is also analyzed.
