| Popis: | The recently reported would-be excess at $125\, GeV$ in invariant mass distribution of $\gamma\, \gamma$ 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 $\sigma\,BR$ for $\gamma\,\gamma$ resonance is predicted to be twice more as the value for the SM Higgs. Decay channel $\gamma\,l^+\,l^-$ may serve as a decisive check of the interpretation. Comment: 6 pages, 4 figures. arXiv admin note: text overlap with arXiv:1110.3137 |
