We present the results of a recent study of meson-exchange two-body currents
in lepton-nucleus inclusive scattering at various kinematics and for different
nuclei within the Relativistic Fermi Gas model. We show that the associated
nuclear response functions at their peaks scale as AkF2ā, for Fermi
momentum kFā going from 200 to 300 MeV/c and momentum transfer q from
2kFā to 2 GeV/c. This behavior is different from what is found for the
quasielastic response, which scales as A/kFā. This result can be valuable in
the analyses of long-baseline neutrino oscillation experiments, which need to
implement these nuclear effects in Monte Carlo simulations for different
kinematics and nuclear targets.Comment: 11 pages, 6 figures, Proccedings of the Workshop "Advanced Aspects in
