On the Analytical Structure of Relativistic Two-body Interaction Current
A.V. Bekzhanov, S.G. Bondarenko, and V. V. Burov

This article is a next step continuing the basic work “Relativistic two-body interaction current in the elastic e-D scattering”. Therefore consideration in this work is completely based on the original one. The work is concentrated principally on investigation of the analytical structure of matrix elements of the interaction part of the Mandelstam current of deuteron in the reaction of elastic electron-deuteron scattering. Description of the complete set of all singularities that appear in this model is given. Also the method of the calculation of moving singularities has been discussed.

Key words: two-body current, deuteron, Bethe-Salpeter formalism, separable anzats
