Abstract

Measurements of the differential cross sections for e⁺e^-→μ⁺μ^- and e⁺e^-→τ⁺τ^- at values of s from 52 to 57 GeV are reported. The forward-backward asymmetries and the total cross sections for these reactions are found to be in agreement with predictions of the standard model of the electro-weak interactions. These measurements are used to extract values of the weak coupling constant g_v ^eg_v ^l and g_A ^eg_A ^l, where l = μ or τ.
