Description

Ensembles of magnetic defects successfully explain many properties of confinement and are strongly believed to capture the (infrared) YM path-integral measure. In this work, we motivate and propose a measure to compute center element averages where vortices and chains (with non-Abelian d.o.f. and monopole fusion) are differentiated. When center vortices percolate and monopoles condense, using Julia-Toulouse and related ideas, we suggest that the average is captured by a saddle point and collective modes in a YMH model. In this manner, flux tubes with $N$-ality and Lüscher terms are accommodated in an ensemble picture.
