Static Solution in Source-Free SU(2) Yang-Mills Theory
X. -J. Wang, M. -L. Yan
We show that a non-trivial topological effect breaks the conformal invariance of pure Yang-Mills theory. Thus it is possible that classic particle-like solutions exists in pure non…

Runing of Axial Coupling Constant
X. -J. Wang, M. -L. Yan
We illustrate that both of massless pseudoscalar meson fields and constitutent quark fields are dynamical field degrees of freedom in energy region between chiral symmetry spontane…

Light Quark Masses to All Orders of Chiral Expansion
X. -J. Wang, M. -L. Yan
We study light (current) quark masses in framework of chiral constitutent quark model. In our calculation the current quark masses are defined uniquely, and all order effects of th…
