In what way does the Standard Model imply the existence of the Higgs Boson? TIA.

I have been around the block on this. The Higgs field breaks the electroweak symmetry U(2) = SU(2)xU(1) the transferring 3 Goldstone boson components to the weak interaction bosons as longitudinal components. A quantum field with a longitudinal component usually has a mass.

Bear with me; what is electroweak symmetry, and why does it need to be broken? TIA, AG

What is the contribution of the Higgs Field, as a per cent, to the vacuum energy? Isn't the Higgs field, a defacto introduction to an ether theory? Isn't the vacuum energy another name for the Cosmological Constant? TIA, AG

The "Higgs boson" is already a component of the Standard Model.

     The Standard Model includes members of several classes of elementary particles:
  

        The Higgs boson 
                plays a unique role in the Standard Model
                is a key building block in the Standard Model

So the Higgs boson is already there in the Standard Model.

The Standard Model is one big mess.

It is an ether, but not specifically for light; ubiquitous, a limited explanation of mass, for some non composite particles. Can't you guys admit it? AG

What's a "mess", if anything, is our understanding of how this system of particles came into being. If you look at the quark masses, it's hard to imagine some unifying principle for their origins. It seems more a result of some random generating process. We have little to no clue what caused the BB, what started and ended (if it did) inflation, or why the Higgs Field turned on, and so forth.
