Large logarithmic rescaling of the scalar condensate: new lattice evidences
P. Cea, M. Consoli, L. Cosmai
Abstract
Using two different methods, we have determined the rescaling of the scalar condensate Z Zϕ near the critical line of a 4D Ising model. Our lattice data, in agreement with previous numerical indications, support the behavior Zϕ (Λ), Λ being the ultraviolet cutoff. This result is predicted in an alternative description of symmetry breaking where there are no upper bounds on the Higgs boson mass from `triviality'.
