Abstract
We study the low energy behavior of the four-dimensional nonlinear sigma model with anomaly using the 2+∊ expansion and renormalization group methods. It is shown that the theory has a non-trivial ir stable fixed point, in addition to the usual trivial fixed point. If pions happen to exist in the non-trivial phase, their propagator would scale at low energies with anomalous exponents.
