Statistical-model analysis ofee¯annihilation

We use a statistical model including both pions and kaons to analyze data on $e\overline{e}$ annihilation. Effects due to the finite size of the pion and kaon mass are included, and both are found to be significant. Good approximations are introduced which do not require computer evaluations of phase-space integrals or infinite sums. Using one parameter we obtain satisfactory fits to charged multiplicities, the $\pi$ to $K$ ratio, and the shape of one-particle inclusive cross sections. Another parameter, which fixes the scale of the total cross section, gives a satisfactory normalization for the one-particle inclusive cross section and for the four- and six-charged-pion exclusive cross sections when it is chosen in agreement with the quark model.
