| contents | A calculation of the two-particle two-hole contribution to the semi-inclusive $(ν_μ,μ^-N)$ cross section on carbon is performed in the framework of the relativistic Fermi gas model. The process is driven by meson-exchange currents encompassing all contributions involving the exchange of a single pion and the excitation of a $Δ$ resonance. The calculation is validated against the inclusive $(ν_μ,μ^-)$ response functions already existing in the literature, and then extended for the first time to the semi-inclusive channel. Results are presented both at fixed neutrino energy and folded with the T2K neutrino flux. |
