A 2-FORM FORMULATION OF THE VECTOR-TENSOR MULTIPLET IN CENTRAL CHARGESUPERSPACE

A two-from formulation for the N = 2 vector-tenser multiplet is constr ucted using superfield methods in central charge superspace. The N = 2 non-Abelian standard supergauge multiplet in central charge superspac e is also discussed, as is with the associated Chem-Simons form. We gi ve the constraints, solve the Bianchi identities and present the actio n for a theory of the vector-tenser multiplet coupled to the non-Abeli an supergauge multiplet via the Chem-Simons form.
