On the dynamics of color magnetic monopoles in full QCD
V. Bornyakov, H. Ichie, S. Kitahara +8
We present first results on the dynamics of monopoles in full QCD with N_f=2 flavors of dynamical quarks. Among the quantities being studied are the monopole density and the monopo…
Lattice monopole action in pure SU(3) QCD
K. Yamagishi, S. Kitahara, T. Suzuki
We obtain an almost perfect monopole action numerically after abelian projection in pure SU(3) lattice QCD. Performing block-spin transformations on the dual lattice, the action fi…
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…
Monopoles and hadron spectrum in quenched QCD
T. Okude, S. Kitahara, O. Miyamura +2
We study quenched hadron spectra with Wilson fermion in abelian gauge fields extracted by maximal abelian projection and in fields induced by monopoles on and $ 1…
Various representations of infrared effective lattice QCD
S. Kato, M. N. Chernodub, S. Kitahara +3
We study various representations of the infrared effective theory of SU(2) gluodynamics starting from the monopole action derived recently. We determine the coupling constants in t…
Critical exponents and abelian dominance in QCD
Shinji Ejiri, Shun-ichi Kitahara, Tsuneo Suzuki +1
The critical properties of the abelian Polyakov loop and the Polyakov loop in terms of Dirac string are studied in finite temperature abelian projected QCD. We evaluate the…
