Query: Resummation in Heavy Quark and Jet Cross Sections   We discuss corrections from the elastic limit (partonic threshold) in
hadronic hard-scattering cross sections. We show why these corrections can be
large at all orders in perturbation theory, and describe their resummation to
arbitrary logarithmic accuracy. In particular, we discuss the role of color
exchange in the hard scattering. This enables us to generalize the resummation
of the Drell-Yan cross section to QCD reactions.
  As an example, we give the explicit resummed hard-scattering cross section
for heavy-quark production through light quark annihilation, which takes into
account next-to-leading logarithms to all orders.
