Topological Compressibility of the Yang-Mills Vacuum: A Semiclassical Prediction for Lattice QCD

We treat the areal density of centre vortices as the order parameter of a homogeneous Ginzburg-Landau functional for the SU(3) vacuum. The quadratic coefficient is fixed, with no free parameters, by the one-loop thick-vortex effective action of Diakonov and Maul, which is negativ...

The Scalar Glueball and the Trace Anomaly: Phenomenological Outlook and Open Lattice Challenges for a Dilaton Eective Model of Pure SU(3)

A dilaton effective model of pure SU(3) gauge theory, whose logarithmic potential is fixed by trace-anomaly matching rather than assumed, is confronted with continuum lattice data. Inverting the anomaly relation gives the dilaton vacuum expectation value χ0 = 304 ± 30 MeV, the st...
