The process $p+p\to W^\pm W^+ W^-$ with lepton decays of $W$-bosons is shown to be promising for improving conditions for studies of parameter $\lambda$, which is the anomalous triple $W$-bosons interaction coupling constant., Comment: 8 pages, 2 figures

We are considering a possibility for detecting non-perturbative effect in process of top pair production in association with a high $p_T$ photon. Starting from previous results on two solutions for a spontaneous generation of wouldbe effective interaction of a top pair with a pair of electro-weak bosons, we show, that a solution with effective cut-off $\Lambda \simeq 10^2\,TeV$ is already contradicting to existing data, while the other one with $\Lambda \simeq 10^{16}\,TeV$ (just the Planck scale) could be reconciled with data and give predictions for process $p+p\to\bar t t \gamma+X$, which could be effectively checked at the LHC with $\sqrt{s}=13\,TeV$. The confirmation of the predictions would mean a strong support for the existence of non-perturbative effects in the electro-weak interaction., Comment: 5 pages, 2 figures, corrections made, typos corrected

Assuming an existence of an anomalous triple electro-weak bosons interaction being defined by coupling constant $\lambda$, we calculate its contribution to interactions of the Higgs with pairs of heavy particles. Bearing in mind experimental restrictions $-0.011 < \lambda < 0.011$ we present results for possible effects in processes $p\,p \to W^+ W^- H,\,p\,p \to W^+ Z H,\,p\,p \to W^- Z H,\,p\,p \to \bar t t H $, $p p \to \bar b b H$. Effects could be significant with negative sign of $\lambda$ in associated heavy quarks $t,\,b$ pairs production with the Higgs. In calculations we rely on results of the non-perturbative approach to a spontaneous generation of effective interactions, which defines the form-factor of the three-boson anomalous interaction., Comment: 6 pages, 2 figures, few typos corrected, references added

Recently reported diboson and diphoton excesses at LHC are interpreted to be connected with heavy $WW$ zero spin resonances. The resonances appears due to the wouldbe anomalous triple interaction of the weak bosons, which is defined by well-known coupling constant $\lambda$. The $2\, TeV$ anomaly tentatively corresponds to weak isotopic spin 2 scalar state and the $\gamma\gamma\,\,750\, GeV$ anomaly corresponds to weak isotopic spin 0 pseudoscalar state. We obtain estimates for the effect, which qualitatively agree with ATLAS data. Effects are predicted in a production of $W^+ W^-, (Z,\gamma) (Z,\gamma)$ via resonance $X_{PS}$ with $M_{PS} \simeq 750\,GeV$, which could be reliably checked at the upgraded LHC at $\sqrt{s}\,=\,13\, TeV$. In the framework of an approach to the spontaneous generation of the triple anomalous interaction its coupling constant is estimated to be $\lambda = -\,0.02\pm 0.005$ in an agreement with existing restrictions. Specific predictions of the hypothesis are significant effects in decay channels $X_{PS} \to \gamma\,l^+\,l^-\,, X_{PS} \to l^+\,l^-\,\,l^+\,l^-\,(l = e,\,\mu)$., Comment: 8 pages, 2 figures; title changed, additional estimates introduced, few new references added
