Quasi-elastic neutrino charged-current scattering off ${}^{12}$C: effects of the meson exchange currents and large nucleon axial mass

Abstract

The quasi-elastic scattering of muon neutrino and electrons on a carbon target are analyzed using the relativistic distorted-wave impulse approximation (RDWIA). We also evaluate the contribution of the two-particle and two-hole meson exchange current ($2p-2h$ MEC) to electroweak response functions. The nuclear model dependence of the (anti)neutrino cross sections is studied within the RDWIA+MEC approach and RDWIA model with the large nucleon axial mass. It is shown that the results for the squared momentum transfer distribution $d\sigma /d{Q}^2$ and for invariant mass of the final hadronic system distribution $d\sigma /dW$ obtained within these models are substantially different.
