Neutral-current production of Kþ by atmospheric neutrinos is a background in searches for the proton decay p → Kþν¯. Reactions such as νp → νKþΛ are indistinguishable from proton decays when the decay products of the Λ are below detection threshold. Events with Kþ are identified in MINERvA by reconstructing the timing signature of a Kþ decay at rest. A sample of 201 neutrino-induced neutral-current Kþ events is used to measure differential cross sections with respect to the Kþ kinetic energy, and the nonKþ hadronic visible energy. An excess of events at low hadronic visible energy is observed relative to the prediction of the NEUT event generator. Good agreement is observed with the cross section prediction of the GENIE generator. A search for photons from π0 decay, which would veto a neutral-current Kþ event in a proton decay search, is performed, and a 2σ deficit o...

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.
