    • Abstract

       

      Various types ofN = 4 superconformal symmetries in two dimensions are considered. It is proposed that apart from the well-known cases ofSU (2)and SU(2) × SU(2) ×U (1), their Kac-Moody symmetry can also be SU(2) × (U (1))4. Operator product expansions for the last case are derived. A complete free field realization for the same is obtained
