Charged-current quasielastic neutrino scattering from ${}^{12}$C in an extended superscaling model with two-nucleon emission

Abstract

The quasielastic cross-section of charged-current neutrino and antineutrino scattering on ${}^{12}$C is calculated using an improved superscaling model with relativistic effective mass. Our model encompasses two-particle 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 ${}^{12}$C that have been measured in accelerator experiments.
