Book Description
D* production is studied in the decay chain D* .-->. D° .pi. with the D° observed in the K−.pi.+ mode and the corresponding charge conjugate decays. The results were obtained from a preliminary analysis of an 80 pb−1 data sample of e+e− annihilations at 29 GeV taken with the High Resolution Spectrometer at PEP. The excellent mass resolution of the HRS allows the study of the D* production and decay with very low background. We present the fragmentation function over the range of Z from 0.2 to 1.0.
