## Abstract

In order to make precision measurements of GeV-scale neutrino oscillations a detailed understanding of both GeV-scale neutrino-nucleon scattering cross sections and nuclear effects are essential. To achieve this, many of the latest analyses at the T2K off-axis near detector (ND280) complement existing results by utilising new techniques to measure muon neutrino charged-current interactions without pions in the final state (CC0$\pi$ interactions). These techniques include water subtraction to obtain a double-differential cross section on oxygen and measurements of differential cross sections using proton kinematics or composite proton-muon variables (such as single transverse kinematic imbalance). In this work these latest CC0$\pi$ measurements are presented with a view to demonstrating their potential to provide complementary precision cross-section measurements and innovative probes of nuclear effects.}
