For
those interested, there is an interpretation of
scalar Higgs fields under quantum field theory (see Zeldovich
1986).
Zero
point vacuum fluctations associated with zero point energies
of quantum fields results in a negative energy
equation of state (having tension rather than
pressure). Quantum field
theory can then make predictions about the value of a cosmological
constant and is off by some 120 orders of
magnitude! Works for
inflationary period, but not now.
