Description 
An electroweak model is formulated in a finite, fourdimensional
quantum field theory without a Higgs particle. The W and Z masses
are induced from the electroweak symmetry breaking of oneloop
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
nonlocal 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 nonlocal 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 selfenergy 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
nonlocal deviation from the Standard Model.
