摘要：

In this paper we show that in the noncommutative chiral gauge theories the 4-fermion vertices are finite. The 4 psi vertices appear in linear order in quantization of the theta-expanded noncommutative gauge theories; in all previously considered models, based on Dirac fermions, the 4 psi vertices were divergent and nonrenormalizable.
