The unitary and analytic model is well-suited for the description of the electromagnetic structure of elementary particles as mesons and baryons. Its conception is based on the experimental fact of vector meson creation in the electron-positron annihilation and on the definition of electromagnetic form factor on the Riemann surface with four sheets. The model provides correct asymptotic behavior and respects all known theoretical constraints, such as analyticity, unitarity, norm, etc. The main aim of the topic will be to evaluate, e. g., hadronic contributions to the anomalous magnetic moment of the muon, or to the running QED coupling constant in a space-like region, to investigate the concept of effective form factors and the damped oscillations associated with them. The task of the phd student will be to develop the model, perform numerical calculations using known experimental data, evaluate errors in the evaluation of results. Last but not least, the development of the program implementation of the model will be carried out, mainly using the Python programming language.
