Moreover, it is fully compatible with the Equivalence Theorem and it yields a consistent description of the Higgs boson mass and width, Finally we have also included a phenomenological discussion concerning the applications of this method to the LHC.engjournal articlehttp://www.sciencedirect.com/science/article/pii/0370269396010520 /science/article/pii/0370269396010520http://www.sciencedirect.comhttp://arxiv.org/abs/hep-ph/9607369open access53Strongly Interacting WsSymmetry-BreakingStandard ModelWw ScatteringUnitarityScalarResonancesMatrixBosonsSectorFísica (Física)22 Física
