3 Apr 2013 | | Abstract: | Gluodynamics and two-flavor QCD at non-zero temperature are studied with the
so-called overimproved cooling technique under which caloron solutions may
remain stable. We consider topological configurations either at the first
occuring stable plateau of topological charge or at the first (anti)selfdual
plateau and find the corresponding topological susceptibility at various
temperatures on both sides of the thermal transition or crossover. In pure
gluodynamics the topological susceptibility drops sharply at the deconfinement
temperature while in full QCD it decreases smoothly at temperatures above the
pseudocritical one. The results are close to those calculated by other methods.
We interpret our findings in terms of the (in)stability of calorons with
non-trivial holonomy and their dyon constituents against overimproved cooling. | | Source: | arXiv, 1304.0935 | | Services: | Forum | Review | PDF | Favorites | |
