Scaling Laws and Effective Dimension in Lattice SU(2) Yang-Mills Theory with a Compactified Extra Dimension
Shinji Ejiri, Shouji Fujimoto, Jisuke Kubo
Monte Carlo simulations are performed in a five-dimensional lattice SU(2) Yang-Mills theory with a compactified extra dimension, and scaling laws are studied. Our simulations indic…
An Almost Perfect Quantum Lattice Action for Low-energy SU(2) Gluodynamics
M. N. Chernodub, S. Fujimoto, S. Kato +3
We study various representations of infrared effective theory of SU(2) Gluodynamics as a (quantum) perfect lattice action. In particular we derive a monopole action and a string mo…
A Quantum Perfect Lattice Action for Monopoles and Strings
S. Fujimoto, S. Kato, T. Suzuki
A quantum perfect lattice action in four dimensions can be derived analytically as a renormalized trajectory when we perform a block spin transformation of monopole currents in a s…
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…
