Abstract:
The use of a superspace approach to realise BRST and anti-BRST symmetry is re-examined. It is shown that Sp(2)-superfield prepotentials always arise upon solving the constraints imposed upon the generalized Sp(2)-superfield field strengths. It is proposed that such ‘toy’ models contain features which should be incorporated into “geometrical” formulations of covariant string field theories.
