Abstract
Production of K+ mesons in charged-current nu(mu) 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, d sigma/dT(K), is observed to be relatively flat between 0 and 500 MeV. Its shape is in good agreement with the prediction by the GENIE neutrino event generator when final-state interactions are included, however the data rate is lower than the prediction by 15%.
