We present a measurement of the average multiplicity of φ mesons in B0, B0, and B± meson decays. Using 17.6 fb-1 of data taken at the Υ(4S) resonance by the BABAR detector at the PEP-II e+e- storage ring at the Stanford Linear Accelerator Center, we reconstruct φ mesons in the K+K- decay mode and measure B(B⃗φX)=(3.41±0.06±0.12)%. This is significantly more precise than any previous measurement.

Abstract
We present a measurement of the average multiplicity of φ mesons in B0, B0, and B± meson decays. Using 17.6 fb-1 of data taken at the Υ(4S) resonance by the BABAR detector at the PEP-II e+e- storage ring at the Stanford Linear Accelerator Center, we reconstruct φ mesons in the K+K- decay mode and measure B(B⃗φX)=(3.41±0.06±0.12)%. This is significantly more precise than any previous measurement.
