摘要：

假设存在由耦合常数$λ$定义的反常三重电弱玻色子相互作用，计算了它对Higgs与重粒子对相互作用的贡献.考虑到实验的限制$-0.011 < λ< 0.011$，我们目前的结果可能影响的过程$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$。$λ$的负符号在关联重夸克$t,\,b$对与希格斯粒子的产生中可能是显著的。在计算中，我们依赖于非微扰方法的结果，自发产生的有效的相互作用，它定义了三玻色子异常相互作用的形状因子。

英文摘要：

Assuming an existence of an anomalous triple electro-weak bosons interaction being defined by coupling constant $λ$, we calculate its contribution to interactions of the Higgs with pairs of heavy particles. Bearing in mind experimental restrictions $-0.011 < λ< 0.011$ 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 $λ$ 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.
