Semirelativistic meson-exchange currents in (e,e) and (e,e' p) reactions
(American Physical Society, 2003-07-01)
Electron-induced one-nucleon knockout observables are computed for a moderate to high momentum transfer, making use of semirelativistic expressions for the one-body and two-body meson-exchange current matrix elements. ...

Final state interactions in semi-inclusive neutrino-nucleus scattering: Applications to the T2K and MINERνA experiments
(American Physical Society, 2022)
We present a complete comparison of semi-inclusive νμ−12C cross section measurements by T2K and MINERνA collaborations with the predictions from the SuSAv2-MEC model implemented in the neutrino-nucleus event generator GENIE ...

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 ...

New evaluation of the axial nucleon form factor from electron- and neutrino-scattering data and impact on neutrino-nucleus cross sections
(American Physical Society, 2020)
A joint fit to neutrino-nucleon scattering and pion electroproduction data is performed to evaluate the nucleon axial form factor in the two-component model consisting of a three-quark intrinsic structure surrounded by a ...

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 ...

Emission of neutron-proton and proton-proton pairs in electron scattering induced by meson-exchange currents
(American Physical Society, 2016)
We use a relativistic model of meson-exchange currents to compute the proton-neutron and proton-proton yields in (e,e ) scattering from 12C in the 2p-2h channel. We compute the response functions and cross section with ...

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 ...

Charged-current quasielastic neutrino scattering cross sections on 12 C with realistic spectral and scaling functions
(American Physical Society, 2014)
Charge-current quasielastic (anti)neutrino scattering cross sections on a 12C target are analyzed using a spectral function S(p,E) that gives a scaling function in accordance with the (e,e′) scattering data. The spectral ...

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 ...

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 ...
