| Abstract: | A study is presented of dimuon events from an exposure of BEBC to a wide band beam from the CERN SPS. These data double the available statistics on induced dilepton events observed in bubble chambers. The relative production rate and V0 yield have been measured and found to agree with previous experiments. The analysis of several kinematical variables shows that the gros features of the data agree with the predictions of the GIM model. Some indication exists that part of the signal could be due to quasi elastic production of the “beautiful baryon”, but the statistical significance is too weak to draw definitive conclusions. |
