Description

Currently the Standard Model (SM) is considered as a low-energy approximation of the future fundamental theory describing all interactions. The SM is agreement with almost all experimental data, but also has obvious disadvantages, which are the reason for further, deeper verification of the SM and search for new physics. The deviation from the SM predictions can be interpreted by the emergence of the massive gauge boson – $Z'$. In this case the experimental information can be presented in the form of constraints on the $Z'$ parameters, which can be used to verify the $Z'$ models (SSM, LRM, ALRM, $E_{6}$-models and other).
The improved model-independent constraints on new, effective parameters for the process ${e^+}{e^-}\rightarrow{f}{\bar{f}}(f=\tau,b)$ at the ILC and CLIC are obtained as a result of the research. The technique of further improvement of constraints is presented.
