Abstract
We report on a sample of J mesons coming from secondary vertices, a characteristic of heavyquark decay, detected in the Fermilab Meson West spectrometer. Based on eight signal events in which a J emerges from a secondary vertex occurring in an air-gap region, we obtain an inclusive bb cross section of 75 31 26 nb/nucleon. This result is compared to recent QCD predictions. We have also observed several events in the exclusive decay modes BJ+K and B0J+K0* in which the B mass is fully reconstructed. © 1995 The American Physical Society.
