`Sudakov logs and BN violations in electroweak corrections at the LHC'
Abstract: Electroweak corrections have been studied for a wide range
of processes at the LHC. In most of these studies, only the virtual
corrections are taken into account, as real corrections lead to
different final states in the detectors. In this seminar, I will
review the emergence of Sudakov logarithms in real and virtual
corrections and I will discuss the combination of analytical real and
virtual corrections at the double-logarithmic level. I will consider
gamma/Z+jet and the ratio of the two in detail, presenting results for
the LHC. The combination is found to lead to a partial compensation of
the negative virtual corrections logs, related to the violation of the
Block-Nordsieck(BN) theorem in non-Abelian theories. I will also
briefly comment on other scattering processes, such as QCD dijet
production, W+Z and W+H, just commenting on whether BN violations are
expected for these processes, their origin and how important they are
expected to be.
