The Diagrammatic Method on the Strong Coupling Expansion in Lattice QCD[J]. Acta Scientiarum Naturalium Universitatis SunYatseni, 1988,27(3):58-67.DOI:
We have given a new method on the strong couping expansion in lattice QCD. It has both the advantages of the Feynman diagrams and those of the algcbric method. As an example
We computed the first two order approximations of the|△S|=2 matrix elements on the strong coupling expansion.
