Abstract
We re-examine the action and classical symmetries of the (2, 0) supersymmetric two-dimensional Wess-Zumino-Novikov- Witten model in (2, 0) superspace. The (2, 0) super-Kac-Moody symmetry is shown to be incompatible with the “physical” WZNW action. It is still possible to incorporate the (1, 0) super-Kac-Moody symmetry or the chiral (2, 0) super-Kac-Moody symmetry within the WZNW theory in a way consistent with (2, 0) superconformal invariance.
