摘要

An enhancement in the inclusive cross section for single muons produced in e+e- annihilation at the (4S) is observed, confirming the interpretation that a new bare flavor (B mesons) is produced at the (4S). A branching ratio for BX of (9.43.6)% is obtained. The two-muon decay, BX+- is not observed, providing a 90%-confidence-level upper limit for the branching ratio for that decay of 1.7%. Combining this with our previously reported limit of 5% for BXe+e-, we obtain 1.3% as an upper limit for BXl+l-.
