Triviality of $\phi^4_4$ in the broken phase revisited

High Energy Physics - Lattice 2015-02-13 v1

Abstract

We define a finite size renormalization scheme for ϕ4\phi^4 theory which in the thermodynamic limit reduces to the standard scheme used in the broken phase. We use it to re-investigate the question of triviality for the four dimensional infinite bare coupling (Ising) limit. The relevant observables all rely on two-point functions and are very suitable for a precise estimation with the worm algorithm. This contribution updates an earlier publication by analysing a much larger dataset.
