(lambda Phi^4)_4 theory on the lattice: evidence for a non-trivial rescaling of the scalar condensate

Abstract

A lattice simulation in the broken phase of four-dimensional (lambda Phi^4) theory in the Ising limit suggests that, in the continuum limit, the scalar condensate rescales by a factor different from the conventional wavefunction renormalization. Possible effects on the present bounds of the Higgs mass are discussed.
