  Recent neutrino-nucleus cross-section measurements of observables
characterising kinematic imbalance from the T2K, MicroBooNE and MINERvA
experiments are used to benchmark predictions from widely used neutrino
interaction event generators. Given the different neutrino energy spectra and
nuclear targets employed by the three experiments, comparisons of model
predictions to their measurements breaks degeneracies that would be present in
any single measurement. In particular, the comparison of T2K and MINERvA
measurements offers a probe of energy dependence, whilst a comparison of T2K
and MicroBooNE investigates scaling with nuclear target. In order to isolate
the impact of individual nuclear effects, model comparisons are made following
systematic alterations to: the nuclear ground state; final state interactions
and multi-nucleon interaction strength. The measurements are further compared
to the generators used as an input to DUNE/SBN and T2K/Hyper-K analyses. Whilst
no model is able to quantitatively describe all the measurements, evidence is
found for mis-modelling of A-scaling in multi-nucleon interactions and it is
found that tight control over how energy is distributed among hadrons following
final state interactions is likely to be crucial to achieving improved
agreement. Overall, this work provides a novel characterisation of neutrino
interactions whilst offering guidance for refining existing generator
predictions.
