Massive quark-antiquark production with gluon radiative effects in high-energy spin-polarized electron-positron collisions

The quark-antiquark production cross section, including gluon radiative corrections to order {\ensuremath{\alpha}}_{s} for high-energy spin-polarized electron-positron collisions is obtained. The gluon radiative corrections are functions of the maximum recorded scaled gluon momentum {X}_{g}=\frac{{E}_{g}}{E}and are expressed by gluon form factors {F}_{i}({\overline{m}}_{f}, {X}_{g}) Formulas for form factors are given for all values of...
