Abstract. Using the Lagrangian that was developed on the corresponding principle between the moving medium electrodynamic and quantum field theory the explicit expression for the static polarizability vertex has been obtained. The applications of this vertex for calculations of the imaginary part of doubly virtual Compton scattering amplitude have been demonstrated.
