Abstract

We have studied inclusive D* production using the DELCO detector at PEP. Our technique involved kaon identification in the momentum range above 3.2 GeV/c using a threshold gas erenkov counter. This leads to a model-independent upper limit on D0-D»0 mixing of 8.1% (90% confidence level). We also have measured the charm fragmentation function, which peaks at xPD*(Ebeam2- MD*2)12 of 0.560.06(stat.), and the total cross section for D* production, (D*)=0.1400.021(stat.)0.032(syst.) nb (x>0.3, with radiative correction).
