The running coupling in lattice Landau gauge with unquenched Wilson fermion and KS fermion
Sadataka Furui, Hideo Nakajima
The running coupling of the Wilson fermon(JLQCD/CP-PACS) and that of Kogut-Susskind(KS) fermion(MILC) are measured in the lattice Landau gauge QCD in scheme. The…
Color Confinement in lattice Landau gauge with unquenched Wilson and KS fermions
Hideo Nakajima, Sadataka Furui
The Kugo-Ojima confinement criterion is verified in the unquenched Landau gauge QCD simulation. The valence quark propagator of the Kogut-Susskind fermion with use of the fermion a…
Colour Confinement in the Lattice Landau Gauge QCD Simulation
Sadataka Furui, Hideo Nakajima
The colour confinement criterion proposed by Kugo and Ojima is tested in the lattice Landau gauge QCD simulation. The renormalization effects are studied by measuring the gluon pro…
Numerical study of the Kugo-Ojima criterion and the Gribov problem in the Landau gauge
Hideo Nakajima, Sadataka Furui, Azusa Yamaguchi
The Kugo-Ojima color confinement criterion, which is based on the BRST symmetry of the continuum QCD is numerically tested by the lattice Landau gauge simulation. We first discuss…
On the colour confinement and the minimal surface
Sadataka Furui, Bilal Masud
In the analysis of the energy of the four-quark system obtained in the SU(2) lattice Monte Carlo, the f-model in which the transition potential is expressed in the form $f=f_c exp(…
Numerical tests of the Kugo-Ojima color confinement criterion
Hideo Nakajima, Sadataka Furui
The Kugo-Ojima color confinement criterion, which is based on the BRST symmetry of QCD is numerically tested by the lattice Landau gauge simulation. We first discuss the BRST symme…
