چکیده

Using two different methods, we have determined the rescaling of the scalar condensate Z ≡ Z ϕ near the critical line of a 4D Ising model. Our lattice data, in agreement with previous numerical indications, support the behavior Z ϕ ∼ ln(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'.

Large logarithmic rescaling of the scalar condensate: a subtlety with substantial phenomenological implications

Lattice data, taken since 1998 near the critical line of a 4D Ising model, have been supporting the large logarithmic rescaling of the scalar condensate predicted in the alternative description of symmetry breaking proposed by Consoli and Stevenson. This conclusion has been challenged in a recent paper by Balog et al. In this paper we respond to the criticism of these authors, recapitulate the ...

N ov 2 00 3 Lattice measurement of the rescaling of the scalar condensate

We have determined the rescaling of the scalar condensate Z ≡ Z ϕ near the critical line of a 4D Ising model. Our lattice data, supporting previous numerical indications, confirm the behaviour Z ϕ ∼ ln(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'. There are many computational and an...

The two flavour Schwinger model: scaling of the scalar condensate

We investigate the continuum limit scaling of the scalar condensate in the N f = 2 Schwinger model on the lattice. We employ maximally twisted mass Wilson fermions and overlap fermions. We compute the scalar condensate by taking the trace of the propagator (direct method) and by utilizing the integrated Ward-Takahashi identity. While the scalar condensate comes out consistent using these two me...

In the Standard Model the Fermi constant is associated with the vacuum expectation value of the Higgs field , 'the con-densate', usually believed to be a cutoff-independent quantity. General arguments related to the 'triviality' of Φ 4 theory in 4 space-time dimensions suggest, however, a dramatic renormalization effect in the continuum limit that is clearly visible on the relatively large latt...

Quark Effects in the Gluon Condensate Contribution to the Scalar Glueball Correlation Function

One-loop quark contributions to the dimension-four gluon condensate term in the operator product expansion (OPE) of the scalar glueball correlation function are calculated in the MS scheme in the chiral limit of nf quark flavours. The presence of quark effects is shown not to alter the cancellation of infrared (IR) singularities in the gluon condensate OPE coefficients. The dimension-four gluon...
