  In this work we utilise variables characterising kinematic imbalance in the
plane transverse to an incoming neutrino, which have recently been shown to act
as a direct probe of nuclear effects (such as final state interactions, Fermi
motion and multi-nucleon processes) in $\mathcal{O}$(GeV) neutrino scattering.
We present a methodology to measure the charged current differential
cross-section with no final state pions and at least one final state proton
($CC0\pi+Np, N \geq 1$) in these variables at the near detector of the T2K
experiment (ND280), using the upstream Fine Grained Detector (FGD1) as a
hydrocarbon target. Overall these measurements will allow us to better
understand the impact of nuclear effects on the observables in neutrino
scattering, providing valuable constraints on the systematic uncertainties
associated with neutrino oscillation and scattering measurements for both T2K
and other experiments with similar energy neutrino beams.
