Meson-exchange currents and quasielastic predictions for charged-current neutrino-12C scattering in the superscaling approach
(American Physical Society, 2015-04-07)
We evaluate and discuss the impact of meson-exchange currents (MECs) on charged-current quasielastic neutrino cross sections. We consider the nuclear transverse response arising from two-particle two-hole states excited ...

Pionic correlations and meson-exchange currents in two-particle emission induced by electron scattering
(The American Physical Society, 2010)
Two-particle two-hole contributions to electromagnetic response functions are computed in a fully relativistic Fermi gas model. All one-pion exchange diagrams that contribute to the scattering amplitude in perturbation ...

Semi-inclusive charged-current neutrino-nucleus cross sections in the relativistic plane-wave impulse approximation
(American Physical Society, 2020)
Neutrino-nucleus quasielastic scattering is studied in the plane-wave impulse approximation for three nuclear models: the relativistic Fermi gas (RFG), the independent-particle shell model (IPSM), and the natural ...

SuSAv2 Model for Inelastic Neutrino-nucleus Scattering
(American Physical Society, 2022)
The susperscaling model SuSAv2, already available for charged-current neutrino-nucleus cross sections in the quasielastic region, is extended to the full inelastic regime. In the model the resonance production and deep ...

Global analysis of parity-violating asymmetry data for elastic electron scattering
(American Physical Society, 2014-08-01)
We perform a statistical analysis of the full set of parity-violating asymmetry data for elastic electron scattering including the most recent high precision measurement from Q-weak. Given the basis of the present analysis, ...

Relativistic description of final-state interactions in neutral-current neutrino and antineutrino cross sections
(American Physical Society, 2013)
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 ...

Semirelativistic description of quasielastic neutrino reactions and superscaling in a continuum shell model
(American Physical Society, 2005-06-01)
The so-called semirelativistic expansion of the weakly charged current in powers of the initial nucleon momentum is performed to describe charge-changing, quasielastic neutrino reactions (νμ,μ−) at ...

Scaling function, spectral function, and nucleon momentum distribution in nuclei
(American Physical Society, 2011)
The link between the scaling function extracted from the analysis of (e,e') cross sections and the spectral function/momentum distribution in nuclei is revisited. Several descriptions of the spectral function based on the ...

Angular distribution in two-particle emission induced by neutrinos and electrons
(American Physical Society, 2014-09-22)
The angular distribution of the phase space arising in two-particle emission reactions induced by electrons and neutrinos is computed in the laboratory (Lab) system by boosting the isotropic distribution in the center of ...

Asymmetric relativistic Fermi gas model for quasielastic lepton-nucleus scattering
(American Physical Society, 2018)
We develop an asymmetric relativistic Fermi gas model for the study of the electroweak nuclear response in the quasielastic region. The model takes into account the differences between neutron and proton densities ...
