We investigate the inter-quark potential in the maximally Abelian (MA)
gauge in SU(3) quenched QCD on a fine lattice at beta=6.4 (a=0.058 fm).
Remarkably, we find almost perfect Abelian dominance of the string
tension or the quark confining force on the fine lattice [1].
Thus, the confinement phenomenon in QCD can be well described only with
Abelian variables in the MA gauge.

In the lattice QCD formalism, we analytically derive a relation between the Polyakov loop and Dirac modes on the lattice where the temporal size is odd and link-variables are temporally periodic. The Polyakov loop is an order parameter for quark confinement and low-lying Dirac modes are essential for chiral symmetry breaking. Remarkably, from the relation, we find that low-lying Dirac modes...

The most important probes for the phase states of a four-dimensional gauge field theory are the Wilson and t'Hooft line operators that are defined on one-dimensional curves in the space-time. However, for more detail understanding of four-dimensional gauge field theory dynamics and vacuum topology we need additional probes expressed by operators defined on the subspaces with higher dimensions....

Mesons constructed from the quark propagators without the lowest-lying eigenmodes of the Dirac operator reveal not only restored chiral and U(1)_A symmetries, but actually a higher symmetry. All possible
chiral and U(1)_A multiplets for the states of the same spin are degenerate, i.e. the energy of the
observed quantum levels does not depend on the spin orientation of quarks and their...
