摘要：

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