Connection of different parametrizations of theproton electromagnetic current operator in discrete symmetries violation case

In this paper field and canonical parameterizations of matrix elements of proton electromagnetic current operator in discrete symmetries violation case were reviewed. The main principles of field and canonical operator parameteri- zations were described. The connection between proton form-factors in field and canonical parametrization has been constructed. Physical interpretation of the proton electromagnetic current odd part formfactors in canonical parametriza- tion has been obtained. Opportunity of using obtained results for solving the actual problems of proton electromagnetic structure theory - the non-rosenbluth ep-scattering problem and the proton radius puzzle - was discussed.
