Abstract

Using a sample of 9.6 × 10 BB̄ meson pairs collected with the CLEO detector, we have fully reconstructed 135 B →ψ K and 526 B →ψ K candidates with very low background. We fitted the ψ K invariant mass distributions of these B meson candidates and measured the masses of the neutral and charged B mesons to be M(B )=5279.1±0.7[stat]±0.3[ syst] MeV/c and M(B )=5279.1±0.4[stat]±0.4[ syst] MeV/c . The precision is a significant improvement over previous measurements. ©2000 The American Physical Society. 6 0 (′) 0 + (′) + (′) 0 2 + 2 S
