Study of D-star mesons produced in electron positron annihilations at 4.14 GeV center of mass energy

Charmed D* mesons produced in e+e-annihilations at a center of mass energy of 4.14 GeV are observed by the Mark III detector at SPEAR. The recoil mass spectrum of the D mesons is used to extract the branching fractions of the charged and neutral D*. Measurements are presented for the two decay modes of the D*O (-'yDo, and :71'0DO) and the three decay modes of the D*+ (-'yD+, :71'0D+ , and :71'+ DO). The quasi-two-body D* D+iY'D, D* D* and two-body DD cross sections are measured. The decay of the D*+ to :71'+ DO is exploited in a search for wrong strangeness events.
