Numerical study of the SU(2) Yang-Mills vacuum state: Much ado about nothing?

Abstract

Numerical results for relative weights of test gauge-field configurations in the vacuum of the SU(2) lattice gauge theory in (3+1) dimensions are compared with expectations following from various proposals for the Yang-Mills vacuum wave functional that interpolate between the free-field limit and the dimensional-reduction form.
