Abstract

We report MINERvA's first measurement of inclusive charged-current νˉμ\barν_μ cross sections on carbon, hydrocarbon, iron, and lead, and their ratios to the cross section on hydrocarbon, as functions of the antimuon transverse momentum, pTp_{\mathrm{T}}. Using a wide-band νˉμ\barν_μ beam with mean energy ∼6 GeV\sim 6~\text{GeV}, these measurements probe all interaction modes, including the transition from resonance production to deep-inelastic scattering. The total uncertainties are typically 5−10%5-10\% for the absolute cross sections and 2−5%2-5\% for the ratios. Comparisons with multiple neutrino interaction models reveal significant discrepancies in the pTp_{\mathrm{T}} dependence, particularly for heavier nuclei. The disagreements are most pronounced at low pTp_{\mathrm{T}} but extend across the full pTp_{\mathrm{T}} range, indicating missing or mis-modelled nuclear effects.
