LHC would-be γ\,γ excess as a non-perturbative effect of the electro-weak interaction
Abstract
The recently reported would-be excess at 125\, GeV in invariant mass distribution of γ\, γ and of l+\,l+\,l-\,l- obtained in the course of the Higgs boson search at LHC is tentatively interpreted as a scalar bound state of two W. Non-perturbative effects of EW interaction obtained by application of Bogoliubov compensation approach lead to such bound state due to existence of anomalous three-boson gauge-invariant effective interaction. The application of this scheme gives satisfactory agreement with existing data without any adjusting parameter but the bound state mass 125\,GeV, while σ\,BR for γ\,γ resonance is predicted to be twice more as the value for the SM Higgs. Decay channel γ\,l+\,l- may serve as a decisive check of the interpretation.
