LHC would-be $γ\,γ$ excess as a non-perturbative effect of the
electro-weak interaction    [PDF]

Boris A. Arbuzov, Ivan V. Zaitsev

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.
