Meson-exchange currents and final-state interactions in quasielastic electron scattering at high momentum transfers
(The American Physical Society, 2010)
The effects of meson-exchange currents (MEC) are computed for the one-particle one-hole transverse response function for finite nuclei at high momentum transfers q in the region of the quasi-elastic peak. A semirelativistic ...

Quasielastic scattering from relativistic bound nucleons: Transverse-longitudinal response
(American Physical Society, 1999-12-27)
Predictions for electron induced proton knockout from p1/2 and p3/2 shells in 16O are presented using various approximations for the relativistic nucleonic current. Results for differential cross section, transverse-longitudinal ...

Inclusive electron scattering within the SuSAv2 meson-exchange current approach
(American Physical Society, 2016-07-25)
We present our recent progress on the relativistic modeling of electron-nucleus reactions and compare our predictions with inclusive 12C (e, e′) experimental data in a wide kinematical region. The model, originally based ...

Relativistic model of 2p-2h meson exchange currents in (anti)neutrino scattering
(IOP Publishing Ltd., 2017-04-26)
We develop a model of relativistic, charged meson-exchange currents (MEC) for neutrino-nucleus interactions. The two-body current is the sum of seagull, pion-in-flight, pion-pole and Δ-pole operators. These operators are ...

Neutrino and antineutrino CCQE scattering in the superScaling approximation from miniBooNE to NOMAD energies
(Elsevier, 2013)
We compare the predictions of the SuperScaling model for charged-current quasielastic muonic neutrino and antineutrino scattering from 12C with experimental data spanning an energy range up to 100 GeV. We discuss the ...

Superscaling in electron-nucleus scattering and its link to CCand NC QE neutrino-nucleus scattering
(AIP Publishing, 2015)
The superscaling approach (SuSA) to neutrino-nucleus scattering, based on the assumed universality of the scaling function for electromagnetic and weak interactions, is reviewed. The predictions of the SuSA model for bot ...

Using electron scattering superscaling to predict charge-changing neutrino cross sections in nuclei
(American Physical Society, 2005-01-01)
Superscaling analyses of few-GeV inclusive electron scattering from nuclei are extended to include not only quasielastic processes, but also the region where excitation dominates. With reasonable assumptions about the ...

Relativistic analyses of quasielastic neutrino cross sections at MiniBooNE kinematics
(American Physical Society, 2011-08-08)
Two relativistic approaches are considered to evaluate the quasielastic double-differential and integrated neutrino-nucleus cross sections. One, based on the relativistic impulse approximation, relies on the microscopic ...

Density dependence of 2p-2h meson-exchange currents
(American Physical Society, 2017-06-12)
We analyze the density dependence of the contribution of meson-exchange currents to the lepton-nucleus inclusive cross section in the two-particle two-hole channel. The model is based on the relativistic Fermi gas, where ...

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 ...
