Relativistic effects in electromagnetic nuclear responses in the quasi-elastic delta region
(Elsevier, 1999-09-20)
A new non-relativistic expansion in terms of the nucleon's momentum inside nuclear matter of the current for isobar electro-excitation from the nucleon is perfo rmed. Being exact with respect to the transferred energy and ...

Superscaling and neutral current quasielastic neutrino-nucleus scattering
(American Physical Society, 2006)
The superscaling approach is applied to studies of neutral current neutrino reactions in the quasielastic regime. Using input from scaling analyses of electron scattering data, predictions for high-energy neutrino and ...

Relativistic effects in two-particle emission for electron and neutrino reactions
(American Physical Society, 2004-08-18)
Two-particle two-hole contributions to electroweak response functions are computed in a fully relativistic Fermi gas, assuming that the electroweak current matrix elements are independent of the kinematics. We analyze the ...

Nuclear effects in electron reactions and their impact on neutrino processes
(AIP Publishing, 2009)
We suggest that superscaling in electroweak interactions with nuclei, namely the observation that the reduced electron-nucleus cross sections are to a large degree independent of the momentum transfer and of the nuclear ...

Nuclear effects in (anti)neutrino charge-current quasielastic scattering at MINER νA kinematics
(IOP Publishing, 2018)
We compare the characteristics of the charged-current quasielastic (anti)neutrino scattering obtained in two different nuclear models, the phenomenological SuperScaling Approximation and the model using a realistic spectral ...

Charged-current neutrino-nucleus reactions within the superscaling meson-exchange current approach
(American Physical Society, 2016-11-18)
We present a detailed study of charged-current neutrino-nucleus reactions in a fully relativistic framework and comparisons with recent experiments spanning an energy range from hundreds of MeV up to 100 GeV within the ...

Mean-field and two-body nuclear effects in inclusive electron scattering on argon, carbon, and titanium: The superscaling approach
(American Physical Society, 2019)
We compare the predictions of the superscaling approach (SuSAv2) model including two-particle two-hole meson-exchange currents with the recent JLab data for inclusive electron scattering on three different targets (C, Ar, ...

Momentum distribution of relativistic nuclei with Hartree-Fock mesonic correlations
(Springer New York, 2002-12)
The impact of Hartree-Fock correlations on the nuclear momentum distribution is studied in a fully relativistic one-boson-exchange model. Hartree-Fock equations are exactly solved to first order in the coupling constants. ...

2p-2h excitations in neutrino scattering: angular distribution and frozen approximation
(Proceedings of Science, 2015)
We study the phase-space dependence of 2p-2h excitations in neutrino scattering using the relativistic Fermi gas model. We follow a similar approach to other authors, but focusing in the phase-space properties, comparing ...

Charged-current inclusive neutrino cross sections in the SuperScaling model
(IOP Publishing, 2016)
SuperScaling model (SuSA) predictions to neutrino-induced charged-current π+ production in the Δ-resonance region are explored under MiniBooNE experimental conditions. The SuSA charged-current π+ results are in good agreement ...
