Book excerpt: The authors study the yields of charged kaons, charged pions, and protons produced in association with B mesons produced in proton-antiproton collisions at center of mass energy 1960 GeV using 355 pb-1 of data collected with the CDF detector at the Fermilab Tevatron. This is the first reported measurements of these yields at a hadron collider. The B mesons are reconstructed using their semileptonic decays: B0 → l+D-X, D- → K+?-?-; B0 → l+D*-X, D*- → ?-$ar{D}$0,$ar{D}$0 → K+?-; B+ → l+$ar{D}$0X, $ar{D}$0 → K+?-; Bs→l+D$-top{s}$ X, D$-top{s}$ → ?-?,? → K+K-. The K, ?, and p are identified using the Time of Flight detector (TOF), the CDF spectrometer, and the specific ionization (dE/dx) measured in the central drift chamber (COT). The fraction of charged kaons produced in association with $ar{B}$$0top{s}$ mesons is found to be larger than the fraction produced in association with the $ar{B}$$0top{s}$ and B- mesons, as expected from naive models of heavy quark hadronization to mesons. The particle species yields are found to be in qualitative agreement with simulation of B meson production in hadron collisions from the PYTHIA Monte Carlo, although the yield of kaons around $ar{B}$$0top{s}$ mesons is found to be larger in the simulation when compared to the data. These studies are important for understanding methods of identifying the flavor of $ar{B}$$0top{s}$ mesons in measurement of $ar{B}$$0top{s}$ flavor oscillations and charge conjugation-parity (CP) violation in $ar{B}$$0top{s}$ meson decays.
