| contents | Higgs boson decay in the large N limit John Morales Rodolfo A. Diaz R. Martinez Rafael Hurtado Física, Astronomía y Matemáticas The Equivalence Theorem is commonly used to calculate perturbatively amplitudes involving gauge bosons at energy scales higher than gauge boson masses. However, when the scalar sector is strongly interacting the theory is non-perturbative. We show that the Equivalence Theorem holds in the large N limit at next-to-leading order by calculating the decay widths h →W+W−___ and h →___ Л+Л−. We also show, in the same scheme ofcalculations, that unitarity is fulfilled for the process h→ Л + Л −. 2005 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46435403 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3A Vol.35 |
