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 ...

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 ...

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 ...

Realistic spectral function model for charged-current quasielastic-like neutrino and antineutrino scattering cross sections on C 12
(American Physical Society, 2019)
A detailed study of charged current quasielastic neutrino and antineutrino scattering cross sections on a C12 target with no pions in the final state is presented. The initial nucleus is described by means of a realistic ...

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. ...

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 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 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 ...
