Abstract
The constraints of CSDR are solved for vector gauge fields over a coset space IOSp (1/2, R)/ OSp (1/2, R) including supertranslations (extended BRST transformations) and ordinary translations (rotations on the circle). The gauge-fixing action incorporates standard ghost and multiplier fields (and their modes) but is nonpolynomial in an additional scalar field ϕ and its modes. There is a new "ϕ-BRST" invariance with respect to ϕ dependent gauge transformations, a bosonic counterpart of the usual "ghost-BRST" invariance. In the Abelian case, ϕ can be integrated out, leading to a formalism equivalent to ordinary covariant gauge-fixing.
