TTP01-03 Sudakov Resummation and Finite Order Expansions of Heavy Quark Hadroproduction Cross

We resum Sudakov threshold enhancements in heavy quark

 hadroproduction for single-heavy quark inclusive and pair-inclusive
 kinematics.  We expand these resummed results and derive analytical
 finite-order cross sections through next-to-next-to-leading order.
 This involves the construction of next-to-leading order matching
 conditions in color space.  For the scale dependent terms we derive
 exact results using renormalization group methods. We study the
 effects of scale variations, scheme and kinematics choice on the
 partonic and hadronic cross sections, and provide estimates for top
 and bottom quark production cross sections.
