| dc.description | We have measured the differential cross sections for the production of $π^{+}$, $K^{+}$, $K^{0}$, $K^{*0}$, $ϕ$, p, $Λ$ and their corresponding antiparticles in separate samples of flavor-tagged $Z^{0}\to$ light-flavor ($u\bar{u}$, $d\bar{d}$, or $s\bar{s}$), $Z^{0}\to c\bar{c}$ and $Z^{0}\to b\bar{b}$ events. Clear flavor dependences are observed, and the results are compared with the predictions of three fragmentation models. We have also performed a direct measurement of $A_{s}$, the parity-violating coupling of the $Z^{0}$ to strange quarks, by measuring the left-right-forward-backward production asymmetry in polar angle of the tagged $s$ quark. Our preliminary result is $A_{s}$ = $0.82\pm 0.10(stat.)\pm 0.07(syst.)$. | |
