Chiral Quark Soliton Model And Nucleon Parton Distribution Functions
Masashi Wakamatsu
The chiral quark soliton model (CQSM) is an effective quark model of baryons maximally taking account of the most important feature of low-energy QCD, i.e., the spontaneous chiral…
Is gauge symmetry vacuous or physical ? : Lessons from the Landau problem as a solvable quantum gauge theoretical system
Masashi Wakamatsu
The gauge symmetry is one of the most important concepts in modern physics, but there are two conflicting views on its meaning or interpretation. The standard view is that local ga…
Revisiting the compatibility problem between the gauge principle and the observability of the canonical orbital angular momentum in the Landau problem
Masashi Wakamatsu, Yoshio Kitadono, Liping Zou +1
As is widely-known, the eigen-functions of the Landau problem in the symmetric gauge are specified by two quantum numbers. The first is the familiar Landau quantum number , wher…
The issue of gauge choice in the Landau problem and the physics of canonical and mechanical orbital angular momenta
M. Wakamatsu, Y. Kitadono, P. -M. Zhang
One intriguing issue in the nucleon spin decomposition problem is the existence of two types of decompositions, which are representably characterized by two different orbital angul…
