Gauge invariance, Lorentz covariance and canonical quantization in nucleon structure studies
Fan Wang, X. S. Chen, W. M. Sun +2
There are different operators of quark and gluon momenta, orbital angular momenta, and gluon spin in the nucleon structure study. The precise meaning of these operators are studied…
Non-monopole magnetic solutions in the Weinberg-Salam model
A. S. Bakry, D. G. Pak, P. M. Zhang +1
The structure of finite energy non-monopole solutions with azimuthal magnetic flux of topological origin is studied in the pure bosonic sector of the Weinberg-Salam model. Applying…
Problems related to gauge invariance and momentum, spin decomposition in nucleon structure study
Fan Wang, W. M. Sun, X. S. Chen +1
How do the quark and gluon share the nucleon momentum? How does the nucleon spin distribute among its constituents? What means the quark and gluon momentum, spin and orbital angula…
Consistent gauge invariant nucleon spin decomposition
D. G. Pak, P. M. Zhang
We consider a non-uniqueness problem of gauge invariant nucleon spin decomposition. A gauge invariant decomposition with a generalized Coulomb constraint for the physical gluon has…
On gauge invariant nucleon spin decomposition
P. M. Zhang, D. G. Pak
A non-uniqueness problem of gauge invariant separation of quark and gluon contributions to nucleon spin is considered. We show that there is a wide number of gauge invariant spin d…
