摘要：

Using a sample of 26 b (b) over bar events, produced in 350 GeV/c pi(-) interactions in a copper target, which includes 13 events where the decays of both B and (B) over bar are well reconstructed, we measure the differential distributions with respect to x(F) and p(T)(2) as well as some two-particle kinematic variables. We also compare our results with a previous experiment and with predictions based on perturbative QCD. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
