Abstract: We calculate the charged-current cross sections obtained at the T2K off-axis near detector for ${\ensuremath{\nu}}_{\ensuremath{\mu}}$-induced events without pions and any number of protons in the final state using transport theory as encoded in the gibuu model. In a comparison with recent T2K data the strength of the 2p2h multinucleon correlations is determined. Linking this to the isospin ($\mathcal{T}$) of the initial nuclear state, it is found that $\mathcal{T}=0$ leads to a significantly better fit of the recent cross sections obtained by T2K, thus achieving consistency of the 2p2h multinucleon correlation contributions between electron-nucleus and neutrino-nucleus reactions.
