    Assuming an existence of an anomalous triple electro-weak bosons interaction being defined by coupling constant λ\lambda, we calculate its contribution to interactions of the Higgs with pairs of heavy particles. Bearing in mind experimental restrictions −0.011<λ<0.011-0.011 < \lambda < 0.011 we present results for possible effects in processes p p→W+W−H, p p→W+ZH, p p→W−ZH, p p→tˉtHp\,p \to W^+ W^- H,\,p\,p \to W^+ Z H,\,p\,p \to W^- Z H,\,p\,p \to \bar t t H , pp→bˉbHp p \to \bar b b H. Effects could be significant with negative sign of λ\lambda in associated heavy quarks t, bt,\,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 adde
