fundamental weak force?

[bsaucer]

According to the Standard Model, the electromagnetic force is mediated by the photon, the color ("strong") force is mediated by gluons, and the so-called electro-weak force is mediated by massive W+, W- and Z0 bosons.

This "electro-weak" force is actually supposed to be a unification between the electromagnetic force and the "weak" force. If these forces can be broken down into its components, we'd have the well-known electromagnetic force, and the bare-bones "weak" force.

But what is this fundamental bare-bones "weak" force? How does it work? and what particles mediate this force? and are the mediating particles necessarily bosons? I assumed that the force would be described by SU(2). The electromagnetic force is U(1) and the unified electro-weak force is SU(2) x U(1).

The fundamental weak force in nature is mankinds errant perception of measure.
