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.
