18 Dec 1995 | | Journal: | Nucl.Phys.Proc.Suppl. 47 (1996) 302-305 | | Subject: | hep-lat | | Affiliation: | RCNP), Atsunori Tanaka (RCNP), Shoichi Sasaki (RCNP), and Osamu Miyamura (Hiroshima Univ. | | Abstract: | The correlation between instantons and QCD-monopoles is studied both in the lattice gauge theory and in the continuum theory. An analytical study in the Polyakov-like gauge, where $A_4(x)$ is diagonalized, shows that the QCD-monopole trajectory penetrates the center of each instanton, and becomes complicated in the multi-instanton system. Using the SU(2) lattice with $16^4$, the instanton number is measured in the singular (monopole-dominating) and regular (photon-dominating) parts, respectively. The monopole dominance for the topological charge is found both in the maximally abelian gauge and in the Polyakov gauge. | | Source: | arXiv, hep-lat/9512024 | | Services: | Forum | Review | PDF | Favorites | |
