透视彩虹梯截断

Perspective on rainbow-ladder truncation

G. Eichmann, R. Alkofer, I. C. Cloet, A. Krassnigg, C. D. Roberts

摘要:

初步看来,对QCD的Dyson-Schwinger方程的彩虹阶梯截断进行系统的修正,将使那些不受对称性严格约束的赝标量和矢量介子性质的质量维计算结果在幅度上均匀地减小。采用彩虹阶梯截断研究的目的和解释重新考虑在这个光。

英文摘要:

Prima facie the systematic implementation of corrections to the rainbow-ladder truncation of QCD's Dyson-Schwinger equations will uniformly reduce in magnitude those calculated mass-dimensioned results for pseudoscalar and vector meson properties that are not tightly constrained by symmetries. The aim and interpretation of studies employing rainbow-ladder truncation are reconsidered in this light.
