摘要：

The cross-section for the reaction e+e- --> bbBARmu+mu- is calculated with a semi-analytical integration of the phase space. Compact formulae are obtained for the total cross section and for invariant mass distributions of the mu+mu- and bbBAR pairs. The background diagrams to ZH production yield analytically cumbersome but numerically small contributions. The numerical results are compared with those from a Monte Carlo approach.
