定域非对易1/p** 2U(1)规范模型的单圈计算和详细分析

One-Loop Calculations and Detailed Analysis of the Localized Non-Commutative 1/p**2 U(1) Gauge Model

Daniel N. Blaschke, Arnold Rofner, Rene I. P. Sedmik

摘要:

本文继承了一系列的文章,描述了我们的企业,以构建一个规范等效的$θ$变形的非交换$p^{-2}$模型最初介绍了Gurau等arXiv:0802.0791。研究表明,Vilar等人arXiv:0902.2956和我们arXiv:0901.1681使用的形式的破缺项来局部化BRST协变运算符$(D^2θ^2D^2)^{-1}$会导致重整化的困难。原因是这个无量纲算子对于模型的任何对称性都是不变的,并且可以插入到任意幂。在本文中,我们讨论了显式单圈计算,并分析了上述问题的产生机制。

英文摘要:

This paper carries forward a series of articles describing our enterprise to construct a gauge equivalent for the $θ$-deformed non-commutative $p^{-2}$ model originally introduced by Gurau et al. arXiv:0802.0791. It is shown that breaking terms of the form used by Vilar et al. arXiv:0902.2956 and ourselves arXiv:0901.1681 to localize the BRST covariant operator $(D^2θ^2D^2)^{-1}$ lead to difficulties concerning renormalization. The reason is that this dimensionless operator is invariant with respect to any symmetry of the model, and can be inserted to arbitrary power. In the present article we discuss explicit one-loop calculations, and analyze the mechanism the mentioned problems originate from.
