As to Jeffrey's email below, I note that he fails to include his own
original email to me, and thus ignores context. As I recall, I lot of
what he described as the "standard model," fairly accurately, was
Georgi-Glashow SU(5) GUT. ***He was not talking at all about QCD or
Wicsak or anything of that nature.*** Everybody today knows that SU(5)
is a "toy" model.
Second, I suggest he read what Jaffe and Witten write at
http://www.claymath.org/millennium/Yang-Mills_Theory/yangmills.pdf
before he blithely asserts that QCD fully explains such thing as
confinement and mesons and short range and there is nothing more to
understand or explain. Read for example on page 3:
"The use of QCD to describe the strong force was motivated by a whole
series of experimental and theoretical discoveries made in the 1960s and
1970s, involving the symmetries and high-energy behavior of the strong
interactions. But classical nonabelian gauge theory is very different
from the observed world of strong interactions; for QCD to describe the
strong force successfully, it must have at the quantum level the
following three properties, each of which is dramatically different from
the behavior of the classical theory:
(1) It must have a mass gap namely there must be some constant
\Lambda > 0 such that every excitation of the vacuum has energy at
least \Lambda.
(2) It must have "quark confinement," that is, even though the theory is
described in terms of elementary fields, such as the quark fields, that
transform non-trivially under SU(3), the physical particle states such
as the proton, neutron, and pion are SU(3)-invariant.
(3) It must have "chiral symmetry breaking," which means that the vacuum
is potentially invariant (in the limit, that the quark-bare masses
vanish) only under a certain subgroup of the full symmetry group that
acts on the quark fields.
The first point is necessary to explain why the nuclear force is strong
but shortranged; the second is needed to explain why we never see
individual quarks; and the third is needed to account for the current
algebra theory of soft pions that was developed in the 1960s.
Both experiment since QCD has numerous successes in confrontation with
experiment and computer simulations, see for example [8], carried out
since the late 1970s, have given strong encouragement that QCD does have
the properties cited above. These properties can be seen, to some
extent, in theoretical calculations carried out in a variety of highly
oversimplified models (like strongly coupled lattice gauge theory, see,
for example, [48]). ***But they are not fully understood theoretically;
there does not exist a convincing, whether or not mathematically
complete, theoretical computation demonstrating any of the three
properties in QCD, as opposed to a severely simplified truncation of it."***
My model is fully consistent with QCD, but expands QCD to also explain
issues that QCD has been unable to explain. Building on accepted
theory and enabling it to explain more without eroding its core premises
or predictions is what good theoretical work is all about. Maxwell was
not hostile to Gauss or Faraday or Ampere because he developed a theory
that merged and thereby extended them all. To the contrary.
I cannot fathom why Jeffry would have taken my comments to him
discussing the limits of SU(5) GUT completely out of context and twisted
them into some form of broadly-based antipathy to QCD and asymptotic
freedom. It just ain't so.
