Tau and muon pair production cross-sections in electron-positron annihilations at $\sqrt{s}$ = 10.58 GeV

Abstract : The calculational precision of $\ee\to\tautau$ and $\ee\to\mumu$ production cross-sections in electron-positron annihilations at \roots = 10.58 \gev are studied for the \kk Monte Carlo simulation program. We determine $\sigma(\ee\to\tautau) = (0.919 \pm 0.003) \nb$ and $\sigma(\ee\to\mumu) = (1.147 \pm 0.005) \nb$, where the error represents the precision of the calculation.
