Abstract

A method for constraining parameters of specific theoretical models by employing model-independent experimental constraints on vertex couplings is presented. The method was tested using the two-Higgs-doublet model (2HDM) model as an example. Constraints on the model parameters are obtained based on experimental data on the coupling parameter \(f_{Z}^{4}\) .
