Superspace interpretation of mass-dependent BRST symmetries in general gauge theories
Bodo Geyer, Dietmar Muelsch
Abstract
A superspace formulation is proposed for the osp(1,2)-covariant Lagrangian quantization of general massive gauge theories. Thereby, osp(1,2) is considered as subalgebra of the superalgebra sl(1,2) which is interpreted as conformal algebra acting on two anticommuting coordinates. The mass-dependent (anti)BRST symmetries of the quantum action in the osp(1,2) superfield formalism are realized as translations associated by mass-dependent special conformal transformations.
