TOPOLOGICAL FLUCTUATIONS AND SUSCEPTIBILITY IN SU(3) LATTICE GAUGE-THEORY

Abstract:

We measure the topological charge density of the (Monte Carlo generated) SU(3) vacuum. Our algorithm involves first smoothening the generated configurations in a way that conserves the total charge in the continuum limit. We work in a range of couplings 5.6 ≤ β ≡ 6/g2 ≤ 6.0 and on lattice sizes up to 164. We find that the topological susceptibility scales like the string tension (within errors). This allows us to extract a value in physical units, Xt 1 4 = 191 ± 16 MeV, in good agreement with...
