Description:
Author(s): M. Shifman, A. Vainshtein, M. B. Voloshin, and V. Zakharov We reanalyze the W -boson loop in the amplitude of the Higgs boson decay into two photons to show the absence of decoupling in the limit of massless W bosons, m W →0 . The Higgs coupling to longitudinal polarizations survives in this limit and generates a nonvanishing contribution in the H → γ γ decay. Thi... [Phys. Rev. D 85, 013015] Published Fri Jan 20, 2012
