Query: Sudakov Resummation and Finite Order Expansions of Heavy Quark
  Hadroproduction Cross Sections   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.
