GENERALIZED N=2 SUPERSYMMETRIC TODA FIELD-THEORIES

In this paper we introduce a class of generalized supersymmetric Toda field theories. The theories are labeled by a continuous parameter and have N = 2 supersymmetry. They include previously known N = 2 Toda th eories as special cases. Using the WZNW-->Toda reduction approach we o btain a closed expression for the bracket of the associated W algebras . We also derive an expression for the generators of the W algebra in a free superfield realization. (C) 1997 Elsevier Science B.V.
