Quantum Holonomy in Three-dimensional General Covariant Field Theory and Link Invariant
W. F. Chen. H. C. Lee, Z. Y. Zhu
We consider quantum holonomy of some three-dimensional general covariant non-Abelian field theory in Landau gauge and confirm a previous result partially proven. We show that quant…
Knots and Particles
L. Faddeev, Antti J. Niemi
Using methods of high performance computing, we have found indications that knotlike structures appear as stable finite energy solitons in a realistic 3+1 dimensional model. We hav…
Meson Exchange and Pion Rescattering Contributions to the Cross Section for
U. van Kolck, G. A. Miller, D. O. Riska
Short range meson-exchange mechanisms such as contribute significantly to the amplitude for near threshold in addition to pion rescattering. The un…
Two-Loop Finiteness of Chern-Simons Field Theory in Background Field Method
M. Chaichian, W. F. Chen
We perform two-loop calculation of Chern-Simons in background field method using the hybrid regularization of higher-covariant derivative and dimensional regularization. It is expl…
Gauss Law Constraints in Chern-Simons Theory From BRST Quantization
M. Chaichian, W. F. Chen, Z. Y. Zhu
The physical state condition in the BRST quantization of Chern-Simons field theory is used to derive Gauss law constraints in the presence of Wilson loops, which play an important…
Differential Regularization of Topologically Massive Yang-Mills Theory and Chern-Simons Theory
W. F. Chen, H. C. Lee, Z. Y. Zhu
We apply differential renormalization method to the study of three-dimensional topologically massive Yang-Mills and Chern-Simons theories. The method is especially suitable for suc…
