Associated heavy quarks pair production with Higgs as a tool for a search for non-perturbative effects of the electroweak interaction at the LHC

Abstract

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 $pp\to W^{+}{W}^{-}H,pp\to W^{+}ZH,pp\to W^{-}ZH,pp\to \bar{t}tH$, $pp\to \bar{b}bH$. 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.
