Iv. Tyutin et Ss. Shakhverdiev, RENORMALIZATION AND CONSERVATION OF A NEW GHOST NUMBER IN THE SP(2) FORMALISM, Physics of atomic nuclei, 60(10), 1997, pp. 1715-1720
The dependences of the renormalized effective action and of the genera
ting functional for vertices on gauge fixing and on a new ghost number
is investigated. It is shown that the structure of these dependences
coincides with that of the unrenormalized action.
