The lambda Phi^4 Miracle: lattice data and the zero-point potential
arXiv:hep-ph/9507408
Abstract
Recent lattice data for the effective potential of lambda Phi^4 theory fits the massless one-loop formula with amazing precision. Any corrections are at least 100 times smaller than is reasonable, perturbatively. This is strong evidence for the "exactness conjecture" of Consoli and Stevenson.
