  We calculate the charged-current cross sections obtained at the T2K off-axis
near detector for $\nu_\mu$-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 (T) of the
initial nuclear state, it is found that T=0 leads to a significantly better fit
of the recent cross sections obtained by T2K, thus achieving consistency of the
2p2h multi-nucleon correlation contributions between electron-nucleus and
neutrino-nucleus reactions.
