Instanton effects on Wilson-loop correlators: a new comparison with numerical results from the lattice

Instanton effects on the Euclidean correlation function of two Wilson loops at an angle $θ$, relevant to soft high-energy dipole-dipole scattering, are calculated in the Instanton Liquid Model and compared with the existing lattice data. Moreover, the instanton-induced dipole-dipole potential is obtained from the same correlation function at $θ=0$, and compared with preliminary lattice data.
