We report on multinucleon effects in low momentum transfer (< 0.8 GeV=c) antineutrino interactions
on plastic (CH) scintillator. These data are from the 2010–2011 antineutrino phase of the MINERvA
experiment at Fermilab. The hadronic energy spectrum of this inclusive sample is well described when a
screening effect at a low energy transfer and a two-nucleon knockout process are added to a relativistic
Fermi gas model of quasielastic, Δ resonance, and higher resonance processes. In this analysis, model
elements introduced to describe previously published neutrino results have quantitatively similar benefits
for this antineutrino sample. We present the results as a double-differential cross section to accelerate the
investigation of alternate models for antineutrino scattering off nuclei.
