Description

We consider a vacuum wavefunctional for SU(N) Yang-Mills theory peaked at thick center vortices. The vacuum average of the 't Hooft within this wavefunctional yields a perimeter law, while that of the Wilson loop yields an area law,, consistent with both criterions for confinement. In this work, we evaluate the topological susceptibility of the vacuum in this framework, and use the results to fix the parameters of the model.
