The Absence of the 4 psi divergence in noncommutative chiral models
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.
