Simultaneous measurement of muon neutrino charged-current single production in CH, C, HO, Fe, and Pb targets in MINERvA
Neutrino-induced charged-current single production in the
resonance region is of considerable interest to
accelerator-based neutrino oscillation experiments. In this work, high
statistics differential cross sections are reported for the semi-exclusive
reaction nucleon(s) on scintillator, carbon,
water, iron, and lead targets recorded by MINERvA using a wide-band
beam with \left \approx 6~GeV. Suppression of the cross
section at low and enhancement of low are observed in both light
and heavy nuclear targets compared to phenomenological models used in current
neutrino interaction generators. The cross-section ratios for iron and lead
compared to CH across the kinematic variables probed are 0.8 and 0.5
respectively, a scaling which is also not predicted by current generators.Comment: 6 pages, 6 figures, 117 pages of supplementary material; submitted to
