Description

On the basis of 2000 Y, Y' and Y'' events obtained in π--W interactions at 194 GeV/c we extract a value for the cross section times the branching ratio of Bsub(μμ)sigma=(0.96+-0.04+-0.17) pb nucleon-1. The (Y'+Y'')/Y ratio is found to be 0.53+-0.19. The observed differential chisub(F) and Psub(T) distributions are compared with those of the Drell-Yan continuum, and the cross section and the chisub(F) distribution are compared with theoretical predictions.
