  The O(alpha) virtual weak radiative corrections to many hadron collider
processes are known to become large and negative at high energies, due to the
appearance of Sudakov-like logarithms. At the same order in perturbation
theory, weak boson emission diagrams contribute. Since the W and Z bosons are
massive, the O(alpha) virtual weak radiative corrections and the contributions
from weak boson emission are separately finite. Thus, unlike in QED or QCD
calculations, there is no technical reason for including gauge boson emission
diagrams in calculations of electroweak radiative corrections. In most
calculations of the O(alpha) electroweak radiative corrections, weak boson
emission diagrams are therefore not taken into account. Another reason for not
including these diagrams is that they lead to final states which differ from
that of the original process. However, in experiment, one usually considers
partially inclusive final states. Weak boson emission diagrams thus should be
included in calculations of electroweak radiative corrections. In this paper, I
examine the role of weak boson emission in those processes at the Fermilab
Tevatron and the CERN LHC for which the one-loop electroweak radiative
corrections are known to become large at high energies (inclusive jet, isolated
photon, Z+1 jet, Drell-Yan, di-boson, t-bar t, and single top production). In
general, I find that the cross section for weak boson emission is substantial
at high energies and that weak boson emission and the O(alpha) virtual weak
radiative corrections partially cancel.
