Abstract

The production rate of charged D* mesons in jets has been measured in 1.8-TeV p»p collisions at the Fermilab Tevatron with the Collider Detector at Fermilab. In a sample of approximately 32 300 jets with a mean transverse energy of 47 GeV obtained from an exposure of 21.1 nb-1, a signal corresponding to 25.0±7.5(stat)±2.0(syst) D*±K events is seen above background. This corresponds to a ratio N(D*++D*-)/ N(jet) =0.10±0.03±0.03 for D* mesons with fractional momentum z greater than 0.1. © 1990 The American Physical Society.
