Measurement of the B-0 and B+ meson masses from B-0 ->psi((')) K-S(0) and B+->psi((')) K+ decays
Using a sample of 9.6 × 106BB̄ meson pairs collected with the CLEO detector, we have fully reconstructed 135 B0→ψ(′)KS0 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 charg...
