An electroweak model with running coupling constants described by an energy dependent entire function is utraviolet complete and avoids unitarity violations for energies above 1 TeV. The action contains no physical scalar fields and no Higgs particle and the physical electroweak model fields are local and satisfy microcausality. The W and Z masses are compatible with a symmetry breaking SU(2)L×U(1)Y U(1)em , which retains a massless photon. The vertex couplings possess an energy scale > 1 TeV predicting scattering amplitudes that can be tested at the LHC.
