Abstract

We have measured the inclusive branching ratio for BX to be (1.09±0.16±0.21)%, and the exclusive branching ratios for B-K- and B»0 *0 to be (0.09±0.05)% and (0.41±0.18)%, respectively. The mass difference between neutral and charged B mesons is 1.1±2.1 MeV, while the difference between the mass of (4S) and twice the mean B-meson mass is 18.5±3.0 MeV. The momentum distribution implies a substantial two-body decay (in agreement with direct measurements), but also some combination of BX with MX>1.5 GeV, and BX.
