Study of D*+ production in νμ charged current interactions in the NOMAD experiment

A search was made among νμ charged current events collected in the NOMAD experiment for the reaction: νμ +N →μ− +D+ + hadrons →D0 + π+ →K− + π+. A high purity D+ sample composed of 35 events was extracted. The D+ yield in νμ charged current interactions was measured to be T = (0.79 ± 0.17(stat.) ± 0.10(syst.))%. The mean fraction of the hadronic jet energy taken by the D+ is 0.67 ± 0.02(stat.) ± 0.02(syst.). The distributions of the fragmentation variables z, PT 2 and xF for D+ are also presented.
