CURRENT-ALGEBRA OF SUPER WZNW MODELS

We derive the current algebra of supersymmetric principal chiral model s with a Wess-Zumino term. At the critical point one obtains two commu ting super-affine Lie algebras as expected, but, in general, them are intertwining fields connecting both right and left sectors, analogousl y to the bosonic case. Moreover, in the present supersymmetric extensi on we have a quadratic algebra, rather than an affine Lie algebra, due to the mixing between bosonic and fermionic fields; the purely fermio nic sector displays an affine Lie algebra as well.
