“…This indeed again yields T c / √ σ = 0.59, buttressing the interpolation procedure used above. Another possibility, which will be reported in detail elsewhere [28], lies in using a larger data set, with N t = 1, 2, 3, for the interpolation. This yields deviations of the order of 10 % in the determination of the physical point, giving another indication of the amount of uncertainty.…”

A random vortex world-surface model for the infrared sector of Sp(2) Yang-Mills theory is constructed. The Sp(2) gauge group, while allowing for the same set of center vortex fluxes as the SU(2) gauge group, induces a significantly different dynamics on those vortex fluxes, which manifests itself in a first-order deconfinement phase transition. As shown by the construction presented here, a new vortex effective action term which can be interpreted in terms of a vortex stickiness can be used to drive the deconfinement transition towards first-order behavior. The available data from lattice Sp(2) Yang-Mills theory are reproduced quantitatively and, in addition, predictions for the behavior of the spatial string tension at high temperatures are presented.
