Description

The analytic expressions for the production cross sections of polarized bottom and top quarks in e+e- annihilation are explicitly derived at the one-loop order of strong interactions. Chirality-violating mass effects will reduce the longitudinal spin polarization for the light quark pairs by an amount of 3%, when one properly considers the massless limit for the final quarks. Numerical estimates of longitudinal spin polarization effects in the processes e+e- → b''b-bar''(g) and e+e- → t''tbar'' (g) are presented. (author)
