MEASUREMENT OF THE B+/B0 PRODUCTION RATIO FROM THE UPSILON(4S) MESON USING B+ -> J/PSI K+ AND B0 -> J/PSI K0{sub S} DECAYS
We report a measurement of the production ratio of charged and neutral B mesons from {Upsilon}(4S) decays based on the ratio of efficiency-corrected yields for the charmonium modes J/{psi} K{sup +} and J/{psi} K{sub s}{sup 0} with 81.9 fb{sup -1} of data collected with the BABAR detector on the {Upsilon}(4S) resonance at 10.580 GeV. We find a value of 1.006 {+-} 0.036(stat) {+-} 0.031(sys) for the ratio R{sup +/0} = {Lambda}({Upsilon}(4S) {yields} B{sup +}B{sup -})/{Lambda}({Upsilon}(4S) {yields} B{sup 0}{bar B}{sup 0}).
