  Semi-inclusive neutrino-nucleus scattering, corresponding to the simultaneous
detection of a lepton and one or more hadrons in the final state, is shown to
be much more sensitive to nuclear effects than the inclusive process. The
theoretical description of the semi-inclusive process is illustrated and some
comparisons of relativistic plane wave impulse approximation (RPWIA)
predictions with recent MicroBooNE, T2K and MINERvA data on argon and carbon
are shown. The merit of new variables constructed to enhance particular nuclear
effects is also illustrated and future developments going beyond the RPWIA
approach are outlined.
