Analytic O(alpha_s) Results for Bottom and Top Quark Production in e+ e- Collisions

M. M. Tung, J. Bernabeu, J. Penarrocha

We present a new derivation of the O(alpha_s) angular distribution of the outgoing $q$-quark in the production process $e^{+}{e}^{-}\to \gamma ,Z\to q\bar{q}(g)$. In our calculation, we exp…
