Description

An electroweak model is formulated in a finite, four-dimensional
quantum field theory without a Higgs particle. The W and Z masses
are induced from the electroweak symmetry breaking of one-loop
vacuum polarization graphs. The theory contains only the observed
particle spectrum of the Standard Model. In terms of the observed
twelve lepton and quark masses, a loop calculation of the
non-local electroweak energy scale $\Lambda_W$ and $\rho$ predicts
the values $\Lambda_W(M_Z)=541.189$ GeV and $\rho(M_Z)=0.99298$,
yielding $s^2_Z\equiv\sin^2\theta_W(M_Z)=0.21686\pm 0.00097$.
Possible ways to detect a non-local signal in scattering
amplitudes involving loop graphs at the LHC are discussed. Fermion
masses are generated from a "mass gap'' equation obtained from
the lowest order, finite fermion self-energy with a broken
symmetry vacuum state. The cross section for $W_L^+
W_L^-\rightarrow W_L^+ W_L^-$ is predicted to vanish for $\sqrt{s}
1 TeV$, avoiding a violation of the unitarity bound. The
Brookhaven National Laboratory measurement of the anomalous
magnetic moment of the muon and the residual difference between
the measured value and the Standard Model can provide a test of a
non-local deviation from the Standard Model.
