Abstract In this work we study the phenomenology of the process pp → W + W − jj at the LHC, in the scenario of the resonant vector boson scattering subprocess W + W − → W + W − which we describe within the effective field theory framework of the Electroweak Chiral Lagrangian. We assume a strongly interacting electroweak symmetry breaking sector in which dynamically generated resonances with masses in the TeV scale appear as poles in the Electroweak Chiral Lagrangian… Expand
