  We consider the effect of next-to-leading order (NLO) electroweak corrections
to Standard Model 2-to-2 processes, taking into account the potentially large
double logarithms originating from both real and virtual corrections. A study
of the leading Sudakov logarithms is presented and Bloch-Nordsieck (BN)
violations are discussed for processes at the CERN Large Hadron Collider. In
particular, we focus on the processes Z/photon+jet and also the ratio of Z to
photon production. This ratio is known to be insensitive to NLO QCD corrections
but this is not expected to be the case for the electroweak corrections. We
also comment on the effect of electroweak corrections and the presence of BN
violation for QCD processes, in particular dijet production, and also for
purely electroweak processes such as W + H and W + Z associated production.
