AB  - We present the first joint measurement of muon neutrino CC0πNp interactions on carbon and oxygen targets, in two double-differential kinematic imbalance (KI) observable spaces, δp_T-δα_T and p_N-cosθ_μ. The measurement employs the ND280 detector of the T2K experiment and includes a detailed description of the event selection used to define signal and control regions, the evaluation of systematic uncertainties, and the signal extraction procedure, together with validation studies supporting a robust cross-section measurement. The results of this analysis indicate that current neutrino-nucleus interaction models do not adequately describe the data, and demonstrate the strong discriminating power of KI observables. This measurement highlights the need for improved theoretical nuclear modeling within neutrino interaction generators to achieve increased precision in neutrino oscillation measurements.
