We report a measurement of the production ratio of charged and neutral B mesons from Υ(4S) decays based on the ratio of efficiency-corrected yields for the charmonium modes J/ψK+ and J/ψKs0 with 81.9 fb-1 of data collected with the BABAR detector on the Υ(4S) resonance at 10.580 GeV.

Abstract

We report a measurement of the production ratio of charged and neutral B mesons from Υ(4S) decays based on the ratio of efficiency-corrected yields for the charmonium modes J/ψK+ and J/ψKs0 with 81.9 fb-1 of data collected with the BABAR detector on the Υ(4S) resonance at 10.580 GeV. We find a value of 1.006 ±0.036(stat)±0.031(syst) for the ratio R+/0= Γ(Υ(4S) → B+B-)/Γ(Υ(4S)→ B0B̄0). © 2004 The American Physical Society.
