Abstract
The yield has been measured in a sample of two-jet continuum events containing both a charm tag as well as an antiproton with the antiproton in the hemisphere opposite the (measurement of charge conjugate modes is implicit throughout). Under the hypothesis that such selection criteria tag events, the branching fraction can be determined by measuring the yield in the same hemisphere as the antiprotons in our sample. Three types of charm tags are used, (from electrons (from and fully reconstructed or or Combining our results obtained from the three independent charm tags, we obtain
