In this paper we study the large N limit of the Standard Model Higgs sector with N lambda, Ng(2) and Ng('2) constant and N being the number of would-be Goldstone bosons, Despite the simplicity of this method at leading order, its results satisfy simultaneously important requirements such as unitarity and the low-energy theorems in contrast with other more conventional approaches. 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. 2023-06-20T18:50:08Z 2023-06-20T18:50:08Z 1996-10-24 journal article 0370-2693 10.1016/0370-2693(96)01052-0 https://hdl.handle.net/20.500.14352/58731 http://www.sciencedirect.com/science/article/pii/0370269396010520 /science/article/pii/0370269396010520 http://www.sciencedirect.com http://arxiv.org/abs/hep-ph/9607369 eng CICYT AEN95-1285-E DE-ACO3-76SFOOO98 open access Elsevier Science BV
