   <hidden 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.
