Abstract:
Probability Pi for the production of i-quark jets (i=u,d, s, c and b) in the e+e- annihilation has been studied based on the electroweak unified standard model. Probability Pi is a function of energy √s. The calculated component ratios of Pu:Pd:Ps:Pc:Pb are 4:1:1:4:1 for √s < 30 GeV, 7:9:9:7:9 for √s=mz=91.16 GeV and 1:1:1:1:1 for √s=78 and 117 GeV, respectively. Using Pc and Pb we have calculated the yields of charmed and bottom mesons in e+e- annihilations in the range of √s=10-178 GeV.
