Study of D^star+ production in muon neutrino charged current interactions in the NOMAD experiment

A search was made among nu mu charged current events collected in the NOMAD experiment for the reaction: nu mu+N--->nu+D(star)^+ hadrons--> D^0+pi^+K^- + pi^+. A high purity D(star)+ sample composed of 35 events was extracted. The D(star)+ yield in nu mu 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(star)+ is 0.67?0.02(stat.)?0.02(syst.). The distributions of the fragmentation variables z, PT2 and xF for D(star)+ are also presented.
