Recent topics of infrared effective lattice QCD
K. Yamagishi, S. Kitahara, S. Ito +7
Three topics concerning infrared effective lattice QCD are discussed. (1)Perfect lattice action of infrared SU(3) QCD and perfect operators for the static potential are analyticall…
String tension and glueball masses of SU(2) QCD from perfect action for monopoles and strings
S. Fujimoto, S. Kato, M. Murata +1
We study the perfect monopole action as an infrared effective theory of SU(2) QCD. It is transformed exactly into a lattice string model. Since the monopole interactions are weak i…
A perfect monopole action for SU(2) QCD
Shouji Fujimoto, Seikou Kato, Tsuneo Suzuki
We found a quantum perfect lattice action in the 4-dimensional monopole current theory which is known as an effective theory in the infrared region of QCD. The perfect monopole act…
On the perfect lattice actions of abelian-projected SU(2) QCD
S. Fujimoto, S. Kato, M. Murata +1
We study the perfect lattice actions of abelian-projected SU(2) gluodynamics. Using the BKT and duality transformations on the lattice, an effective string model is derived from th…
