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…
