Study of D$^{*+}$ and search for D$^{**0}$ production by neutrinos in BEBC

Data from BEBC experiments are combined to provide large statistics for neutrino interactions. Charged D^{*} mesons are produced in (1.22\pm0.25)\% of neutrino and (1.01\pm0.31)\% of antineutrino charged current interactions. The mean fraction of the hadronic laboratory energy taken by the D^{*+} in...

Descripción
Sumario:Data from BEBC experiments are combined to provide large statistics for neutrino interactions. Charged D^{*} mesons are produced in (1.22\pm0.25)\% of neutrino and (1.01\pm0.31)\% of antineutrino charged current interactions. The mean fraction of the hadronic laboratory energy taken by the D^{*+} in these events is 0.59\pm0.03\pm0.08. Less than 18\% of all charged D^{*} mesons from (anti)neutrino interactions are found to be daughters of D^{**0} (at the 90\% confidence level).
