Abstract
We present a calculation of the fully exclusive parton cross sections for heavy-quark production at order O( α S 3) in QCD. Our result includes the Born cross section for producing a Q Q pair, of order O( α S 2), the virtual corrections to the Born cross section, of order O( α S 3), and the cross section for producing a Q Q pair plus a light parton, of order O( α S 3). We can therefore compute distributions in which correlations among the heavy quarks (and, if present, the associated jet) are correctly taken into account up to order O( α S 3). We present some applications of phenomenological interest to top, bottom and charm production at hadron colliders.
