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…
Spin and orbital angular momentum of the tensor gauge field
Xiang-Song Chen, Ben-Chao Zhu, Niall Ó Murchadha
Following the recent studies of the trickiness in spin and orbital angular momentum of the vector gauge fields, we perform here a parallel analysis for the tensor gauge field, whic…
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…
