Sudakov resummation and finite order expansions of heavy quark hadroproduction cross sections - art. no. 114001

We resum Sudakov threshold enhancements in heavy quark hadroproduction for single-heavy-qua-rk inclusive and pair-inclusive kinematics. We expand thes e resummed results and derive analytical finite-order cross sections throug h next-to-next-to-leading order. This involves the construction of next-to- leading order matching conditions in color space. For the scale dependent t erms, we derive exact results using renormalization Group methods. We study the effects of scale variations, scheme and kinematics choice on the parto nic and hadronic cross sections, and provide estimates for top and bottom q uark production cross sections.
