Description
We study the impact of anomalous gauge boson and fermion couplings on the production of W+W− pairs at the LHC. Although constrained to be very small by LEP, anomalous fermion-gauge boson couplings can have important effects in LHC fits to anomalous couplings. Addtionally, we show that the QCD corrections have important effects, in particular when one W boson is longitudinally polarized and the other is transversely polarized. In effective field theory language, we demonstrate that the dimension-6 approximation to constraining new physics effects in W+W− pair production fails at pT∼500−1000 GeV.
Summary
This is a LO and NLO analysis of the SM effective field theory, which doesn't seem to quite match the above categories.
