As a consequence, one expects the one-loop potential to be exact . We present a lattice computation of the effective potential for massless $λΦ^4$ theory which nicely confirms the expectations based on ``triviality''. Our results imply that the magnitude of the Higgs boson mass, beyond perturbation theory, does not represent a measure of the observable interactions in the scalar sector of the standard model.5 pages, RevTeXHigh Energy Physics - TheoryHigh Energy Physics - LatticeHigh Energy Physics - Phenomenologytext
