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

## TL;DR

This paper investigates how anomalous electroweak interactions, characterized by a coupling constant λ, could influence Higgs production with heavy quark pairs at the LHC, potentially revealing non-perturbative effects.

## Contribution

It introduces a non-perturbative approach to evaluate the impact of anomalous triple electroweak boson interactions on Higgs-heavy quark processes at the LHC.

## Key findings

- Effects are potentially significant with negative λ in heavy quark pair production.
- Calculations are based on a non-perturbative model for effective interactions.
- Experimental restrictions on λ are incorporated into the analysis.

## 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 $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.
