abstract = {The quasielastic cross section of charged-current neutrino and antineutrino scattering on 12C is calculated
using an improved superscaling model with relativistic effective mass. Our model encompasses twoparticle
emission induced by neutrinos, which we distinguish into two contributions. The first contribution
arises from meson-exchange currents, and its calculation is performed at a microscopic level. The second
contribution is phenomenological and extracted from the high-energy tail of the scaling function, assumed
to be produced by 2p2h mechanisms where the one-body current plays a role, such as short-range
correlations and interferences with MEC, final-state interaction, etc. The model explicitly includes the
modification of the relativistic effective mass of the nucleon within the relativistic mean field model of
nuclear matter. The meson exchange currents are also consistently calculated within the same model. With
this model, we present predictions for the neutrino and antineutrino cross sections of 12C that have been
measured in accelerator experiments.},
