Art of spin decomposition
Xiang-Song Chen, Wei-Min Sun, Fan Wang +1
We analyze the problem of spin decomposition for an interacting system from a natural perspective of constructing angular momentum eigenstates. We split, from the total angular mom…

A model study of quark number susceptibility at finite temperature beyond rainbow-ladder approximation
Yu Jiang, Liu-Jun Luo, Hong-Shi Zong
In this paper we calculate the quark number susceptibility (QNS) of QCD at finite temperature under the rainbow-ladder and Ball-Chiu type truncation schemes of the Dyson-Schwinger…

Proper identification of the gluon spin
Xiang-Song Chen, Wei-Min Sun, Fan Wang +1
Properties of the recently proposed gauge-invariant gluon spin are studied and compared to the usually defined "gluon polarization" . By explicit 1-loop calculations in a…
