Query: Supersymmetric nonlinear sigma models as anomalous gauge theories   We revisit supersymmetric nonlinear sigma models on the target manifold
$CP^{N-1}$ and $SO(N)/SO(N-2)\times U(1)$ in four dimensions. These models are
formulated as gauged linear models, but it is indicated that the Wess-Zumino
term should be added to the linear model since the hidden local symmetry is
anomalous. Applying a procedure used for quantization of anomalous gauge
theories to the nonlinear models, we determine the form of the Wess-Zumino
term, by which a global symmetry in the linear model becomes smaller in the
action than the conventional one. Moreover, we analyze the resulting linear
model in the $1/N$ leading order. Consequently, we find that the model has a
critical coupling constant similar to bosonic models. In the weak coupling
regime, the $U(1)$ local symmetry is broken but supersymmetry is never broken.
In contrast to the bosonic case, it is impossible to find stable vacua in the
strong coupling regime as far as in the $1/N$ leading order. These results are
straightforwardly generalized to the case of the hermitian symmetric space.
