Abstract

All-order strong coupling simulations have been used to derive precise\nenergies of string states in the confined phase of three dimensional Z(2)\nlattice gauge theory. The behavior of the ground state energy is here compared\nwith predictions of effective string theory. Our new data reported here are\nconsistent with known universal terms of the long string length (L₀)\nexpansion known from effective string models in the continuum limit. Our\nprecision is however still not sufficient to disentangle non-univeral terms of\norder L₀^-7\n
