  We study electroweak Sudakov effects in single W, Z and gamma production at
large transverse momentum using Soft Collinear Effective Theory. We present a
factorized form of the cross section near the partonic threshold with both QCD
and electroweak effects included and compute the electroweak corrections
arising at different scales. We analyze their size relative to the QCD
corrections as well as the impact of strong-electroweak mixing terms. Numerical
results for the vector-boson cross sections at the Large Hadron Collider are
presented.
