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 ...

Analysis of polarized 16 O ( → e , e ′ → p ) observables within the relativistic distorted wave impulse approximation
(American Physical Society, 2004)
Recoil nucleon transferred polarization observables in coincidence quasielastic electron scattering are studied within the relativistic distorted wave impulse approximation. Results for response functions and polarization ...

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 ...

Relativistic current densities for bound spin-orbit partners and the longitudinal-transverse response in (e,ép) processes
(Elsevier, 1998-11-23)
Scalar, baryon and vector-current densities in coordinate and momentum space are calculated within a relativistic mean-field model. The role of the low components of the bound nucleon wave function is investigated in detail ...

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 ...

Charged-current inclusive neutrino cross sections in the SuperScaling model including quasielastic, pion production and meson-exchange contributions
(IOP Publishing, 2015)
Charged current inclusive neutrino-nucleus cross sections are evaluated using the superscaling model for quasielastic scattering and its extension to the pion production region. The contribution of two-particle-two-hole ...

Scaling function and nucleon momentum distribution
(The American Physical Society, 2010)
Scaling studies of inclusive quasielastic electron scattering reactions have been used in the past as a basic tool to obtain information on the nucleon momentum distribution in nuclei. However, the connection between the ...

Constraints in modeling the quasielastic response in inclusive lepton-nucleus scattering
(American Physical Society, 2020)
We show that the quasielastic (QE) response calculated with the superscaling approach (SuSAv2) model, that relies on the scaling phenomenon observed in the analysis of (e,e′) data and on the relativistic mean-field theory, ...
