Direct measurement of the decays of charmed D mesons

Charmed D mesons produced in the decay of the t/1(3770) are observed by the Mark III detector at SPEAR. A new technique is applied to these data to derive D branching fractions which do not rely on the measurement of D production cross sections. Measurements are presented for three decay modes of the D0 ( K-1pi+, K-1pi-1pi+ 1pi+ and K-1pi+ 1pi0 ) and four decay modes of the n+ ( K-1pi+ 1pi+, K-1pi+1pi+1pi0 , K-1pi+ and K-1pi+1pi0 ). The resulting branching fractions are significantly larger than previous measurements.
