On the glueball spectrum in O(a)-improved lattice QCD
UKQCD Collaboration, A. Hart, M. Teper
We calculate the light `glueball' mass spectrum in N_f=2 lattice QCD using a fermion action that is non-perturbatively O(a) improved. We work at lattice spacings a ~0.1 fm and with…
Z2 monopoles in D=2+1 SU(2) lattice gauge theory
A. Hart, B. Lucini, Z. Schram +1
We calculate the Euclidean action of a pair of Z2 monopoles (instantons), as a function of their spatial separation, in D=2+1 SU(2) lattice gauge theory. We do so both above and be…
Vortices and confinement in hot and cold D=2+1 gauge theories
A. Hart, B. Lucini, Z. Schram +1
We calculate the variation with temperature of the vortex free energy in D=2+1 SU(2) lattice gauge theories. We do so both above and below the deconfining transition at T=Tc. We fi…
Monopole clusters, Z(2) vortices and confinement in SU(2)
A. Hart, M. Teper
We extend our previous study of magnetic monopole currents in the maximally Abelian gauge [hep-lat/9712003] to larger lattices at small lattice spacings (20^4 at beta = 2.5 and 32^…
The string tension in the maximally Abelian gauge after smoothing
A. Hart, J. D. Stack, M. Teper
We apply smoothing to SU(2) lattice field configurations in 3+1 dimensions before fixing to the maximally Abelian gauge. The Abelian projected string tension is shown to be stable…
Magnetic monopole clusters, and monopole dominance after smoothing in the maximally Abelian gauge of SU(2)
A. Hart, M. Teper
In the maximally Abelian gauge of SU(2), the clusters of monopole current are found to divide into two distinct classes. The largest cluster permeates the lattice, has a density th…
