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 ...

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 ...

Superscaling of non-quasielastic electron-nucleus scattering
(The American Physical Society, 2009)
The present study focuses on the superscaling behavior of electron-nucleus cross sections in the region lying above the quasielastic peak, especially the region dominated by electroexcitation of the Δ. Non-quasielastic ...

The frozen nucleon approximation in two-particle two-hole response functions
(Elsevier, 2017-04-27)
We present a fast and efficient method to compute the inclusive two-particle two-hole (2p–2h) electroweak responses in the neutrino and electron quasielastic inclusive cross sections. The method is based on two approximations. ...

Superscaling in charged current neutrino quasielastic scattering in the relativistic impulse approximation
(American Physical Society, 2005-12-16)
Superscaling of the quasielastic cross section in charged-current neutrino-nucleus reactions at energies of a few GeV is investigated within the framework of the relativistic impulse approximation. Several approaches are ...

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. ...

Emission of neutron–proton and proton–proton pairs in neutrino scattering
(Elsevier, 2016)
We use a recently developed model of relativistic meson-exchange currents to compute the neutron–proton and proton–proton yields in (νμ,μ−) scattering from 12C in the 2p–2h channel. We compute the response functions and ...

Delta-isobar relativistic meson exchange currents in quasielastic electron scattering
(Elsevier, 2003)
We study the role of the Δ-isobar current on the response functions for high energy inclusive quasielastic electron scattering from nuclei. We consider a general Lagrangian which is compatible with contact invariance and ...

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 models for quasi-elastic neutrino-nucleus scattering
(American Institute of Physics, 2012)
Two relativistic approaches to charged-current quasielastic neutrino-nucleus scattering are illustrated and compared: one is phenomenological and based on the superscaling behavior of electron scattering data and the other ...
