Unitarity Bounds in the Vector Condensate Model of Electroweak Interactions

Abstract

We replace the standard model scalar doublet by a doublet of vector fields and generate masses by dynamical symmetry breaking. Oblique radiative corrections are small if the new vector bosons ($B^{+}$, $B^0$) are heavy. In this note it is shown that the model has a low momentum scale and above $\Lambda \simeq 2$ TeV it does not respect the perturbative unitarity. From tree-graph unitarity the allowed region of $B^{+}(B^0)$ mass is estimated as $m_{B^{+}}\ge 369GeV(m_{B^0}\ge 410$ GeV) at $\Lambda =1$ TeV.
