Abstract

We report measurements of the decays B+K+ and B0K0 using a sample of 231 106 BB pairs collected with the BABAR detector at the PEP-II asymmetric-energy B factory at the Stanford Linear Accelerator Center. The branching fractions are measured to be B(B+K+)=(7.5 1.0(stat)0.7(syst)) 10-6 and B(B0K0)=(4.1-1.4+1. 7(stat)±0.4(syst)) 10-6 for invariant mass below 2.85 GeV/c2. © 2006 The American Physical Society.
