Radiative W production at hadron colliders is an important testing ground for the Standard Model. We consider W γγ production which is sensitive to the quartic WW γγ coupling. Furthermore the Standard Model amplitude for this process contains a radiation zero. We present a calculation of the NLO QCD corrections for W γγ production at the LHC.

We discuss the direct measurement of the trilinear vector boson couplings in present and future collider experiments. The major goals of such experiments will be the confirmation of the Standard Model (SM) predictions and the search for signals of new physics. We review our current theoretical understanding of anomalous trilinear gauge-boson self interactions. If the energy scale of the new physics is ∼ 1 TeV, these low energy anomalous couplings are expected to be no larger than O(10 −2 ).Constraints from high precision measurements at LEP and low energy charged and neutral current processes are critically reviewed.

We investigate the prospects of measuring tlie strange quark distribution function at the Tevatron, using W plus charm quark events. The 1V plus charm quark signal produced by strange quarkgluon fusioid, sg 4 W-c and 3g 4 ' W+E, is approximately 6% of the inclusive W + 1 jet cros8 secticn for jets with a transverse inomentun ~(j) > 10 GeV. We study the sensitivity of the W + charm quark cross section to the perametrizcriion of the strange quark distribution function, and evaluate the various background processes. The different proepectr of tegging the dinriii qunrk with the CDT and Ug detectors are briefly dscussed.
