**Charged Particle Production in Association with ***B*^{0},B^{+},B_{s}^{0} Mesons
This page summarizes the analysis in which yields of *K*^{+}/K^{-}, *π*^{+}/π^{-} and *p/anti-p*
produced in association with *B*^{0}, *B*^{+} and
*B*_{s}^{0} mesons are measured. The primary motivation
for this analysis is to compare the yields of kaons produced in association
with *B*_{s}^{0} mesons with those produced in association
with *B*_{d}^{0} mesons. This is of interest because it
has been hypothesized that *B*_{s}^{0}-K charge
correlations may provide a powerful tag of the *B*_{s}^{0}
flavor at production, and could be used to significantly improve limits on
the *B*_{s}^{0} oscillation frequency.

A complete description of the analysis is available in
CDF Public note 8137.

## Blessed Figures and Tables

Total particle multiplicities in the cone (ΔR<0.7) around
B^{0}, B^{+} and B^{0}_{s} mesons.
Open symbols are measurements based on CDF data, while the solid symbols are
the predictions from `PYTHIA`.

Signals from semileptonic B decays reconstructed in the channels μ^{+}*D*^{-},μ^{+}*D*^{*-}, μ^{+}*D*^{0} and μ^{+}*D*^{-}_{s}.

Signals from semileptonic B decays reconstructed in the channels e^{+}*D*^{-},e^{+}*D*^{*-}, e^{+}*D*^{0} and e^{+}*D*^{-}_{s}.

Fraction of charged particles that are kaons as a function of
p_{T}(track) in a cone (ΔR<0.7) around B^{0}, B^{+} and

probability of finding a kaon produced in association with a
B^{0}_{s} meson is greater than for finding one produced
in association with B^{0} or B^{+}.
