Pm. Lavrov, SUPERFIELD FORMULATION OF THE SP(2)-COVARIANT QUANTIZATION METHOD IN GAUGE-THEORIES, Theoretical and mathematical physics, 107(2), 1996, pp. 602-608
A Lagrange quantization scheme for a general gauge theory based on the
BRST- and anti-BRST-symmetry principles is proposed in the superspace
D = d + 2, where d is the space-time dimension. For superfields. We B
RST- and anti-BRST-transformations are realized as shifts along the au
xiliary (Grassmann) coordinates of the superspace.
