Data-based two-body current contribution to the neutrino-nucleus cross section
Data-based two-body current contribution to the neutrino-nucleus cross section
A phenomenological model of two-body current (2p2h) contribution to neutrino cross section is introduced. Predictions of the Valencia model for 2p2h [J. Nieves et al., Phys. Rev. C 83, 045501 (2011)] are modified using recent $\mathrm{CC}0\ensuremath{\pi}$ measurements from T2K and MINERvA experiments. Our results suggest a significant increase of the …
