非对易手征模型中4 $ψ$发散的不存在

The absence of the 4$ψ$ divergence in noncommutative chiral models

M. Buric, D. Latas, V. Radovanovic, J. Trampetic

摘要:

本文证明了在非对易手征规范理论中4-费米子顶点是有限的。$4ψ$ -顶点在$θ$ -展开的非对易规范理论的量子化中以线性顺序出现;在所有以前考虑过的基于狄拉克费米子的模型中,$4ψ$ -顶点是发散的,不可重整化的。

英文摘要:

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