Unitarity In An Alternative Electroweak Theory

Abstract

An electroweak (EW) model has been investigated (Moffat) in which the energy $E<\mu =\sqrt{\lambda }{M}_W$, where $\lambda$ is a gauge parameter and $M_W$ is the $W$ boson mass. For large enough $\lambda$ the scalar boson mass $\mu =\sqrt{\lambda }{M}_W$ can be heavy enough to avoid detection in LHC experiments. The theory is perturbatively renormalizable for the decoupled scalar interactions. The Born approximation tree graph unitarity can be ensured by postulating that the effective coupling constant $g_{\mathrm{eff}}(s)$ vanishes as $1/\sqrt{s}$ or faster as $s\to \infty$, predicting that the EW interactions become weaker at high energies, and longitudinally polarized $W_L{W}_L\to W_L{W}_L$ scattering does not violate Born approximation tree graph unitarity.
