We present a measurement of the average multiplicity of phi mesons in B-0, (B) over bar (0), and B+/- meson decays. Using 17.6 fb-1 of data taken at the Y(4S) resonance by the BABAR detector at the PEP-II e(+)e(-) storage ring at the Stanford Linear Accelerator Center, we reconstruct phi mesons in the K+K- decay mode and measure B(B-->phiX)=(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 phi mesons in B-0, (B) over bar (0), and B+/- meson decays. Using 17.6 fb-1 of data taken at the Y(4S) resonance by the BABAR detector at the PEP-II e(+)e(-) storage ring at the Stanford Linear Accelerator Center, we reconstruct phi mesons in the K+K- decay mode and measure B(B-->phiX)=(3.41+/-0.06+/-0.12)%. This is significantly more precise than any previous measurement.
