  In the standard model, electro-weak bosons are developed as gauge-fields
initially satisfying an SU(2) $\times$ U(1) local symmetry mediating
interactions with a multi-component field. This symmetry gets broken when the
component of the field associated with the (scalar) Higgs boson acquires a
non-vanishing expectation value, generating masses for weak vector bosons
(W$^+$,W$^-$,Z) as well as a massless photon (A) which couples to electric
charge. Beyond an expression relating the masses of the W and Z bosons, there
are few predictions concerning further relationships involving the Higgs mass
or mixing angle. In this paper, kinematic relationships between unitarily mixed
momentum-space spinors (supplemental to standard electro-weak modeling) will be
developed. These relationships expressed in terms of kinematic invariants are
shown to be consistent with current measured results.
