Description
The method of relative weights is used to extract, from an underlying SU(3) lattice gauge theory at finite chemical potential, an effective theory which depends only on Polyakov line holonomies. The effective theory can be solved by both mean field and complex Langevin methods, and the solutions from the two approaches can be compared. It is found that when the two methods agree, they agree almost perfectly, and when the results disagree, the complex Langevin approach suffers from the branch-cut problem pointed out by Mollgaard and Splittorff.
