Abstract
A search was made among numu charged current events collected in the NOMAD experiment for the reaction: nu(mu) + N --> mu(-) + D*+ + hadrons hooked right arrowD(0) + pi(+) hooked right arrowK(-) + pi(+) A high purity D*+ sample composed of 35 events was extracted. The D*+ 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*+ is 0.67 +/- 0.02(stat.) +/- 0.02(syst.). The distributions of the fragmentation variables z, P-T(2) and x(F) for D*+ are also presented.
