First evidence for center dominance in SU(3) lattice gauge theory

Abelian dominance and gluon propagators in the Maximally Abelian gauge of SU ( 2 ) lattice gauge theory

Propagators of the diagonal and the off-diagonal gluons are studied numerically in the Maximal Abelian gauge of SU(2) lattice gauge theory. We have found a strong enhancement of the diagonal gluons in the infrared region. The enhancement factor is about 50 at our smallest momentum 325 MeV. We have also applied various fits to the propagator formfactors.

Lattice Gauge Theory

Supercomputers have recently become a crucial tool for the quantum field the-orist. Applied to the formalism of lattice gauge theory, numerical simulations are providing fundamental quantitative information about the interactions of quarks, the fundamental constituents of those particles which experience nuclear interactions. Perhaps most strikingly, these simulations have provided convincing e...

The Gribov Ambiguity for Maximal Abelian and Center Gauges in SU(2) Lattice Gauge Theory

The suggestion that a clearer view of confinement could be attained after gauge-fixing was first made by ’t Hooft, who also introduced the maximal abelian gauge (MAG) [1]. For an SU(2) gauge theory, this gauge attempts to suppress the ‘charged’ gauge fields Aμ, A 2 μ, and maximize the ‘abelian’ field Aμ. In the continuum this is done by finding the minimum over the group of gauge transformation...
