Abstract

Production of K⁺ mesons in charged-current ν_μ interactions on plastic scintillator (CH) is measured using MINERvA exposed to the low-energy NuMI beam at Fermilab. Timing information is used to isolate a sample of 885 charged-current events containing a stopping K⁺ which decays at rest. The differential cross section in K⁺ kinetic energy, dσ/dT_K, is observed to be relatively flat between 0 and 500 MeV. Its shape is in good agreement with the prediction by the \textscgenie neutrino event generator when final-state interactions are included, however the data rate is lower than the prediction by 15\%.
