We just made a duplicate page redirect here, here is the content, I don't know if there's anything which needs to be merged in:
Quantam Chromodyanmics, or QCD, is a relavistic quantam-mechanical quage theory of the strong interactions based on the exchange of mass-less gluons between quarks and antiquarks.
QCD is analogous to quantum electrodyanmics (QED) in the field theory of electromagnetic interactions, but with gluon replacing the photon and the 'color' quantam number instead of electric charge. The theory has been tested successfully in high-energy experiments involving muon-nucleon scattering and proton-antiproton collisions.

Non-neutral
Previous versions of this entry were non-neutral in favour lattice theory and I tried to mitigate this. It seems I may have undone some alterations which was inadvertent and unexpected?!?
Poor grammar causes confusion
If I knew more about this subject, I would try to make the correct changes myself, but I am not so lucky.
The second sentence in this article doesn't make any sense:
"Because of its special property [property], it was first proposed in the early 1970s by [people]"
This means that QCD was proposed because of this property. It doesn't seem right that the property itself didn't spark the proposal, and if by some strangeness, it did, that should be explained.
- I apologize, I'm not a native speaker and "Because of its..." is my sentence. But could you explain your objection more comprehensibly? I am simply not understanding what can be unclear about the sentence. QCD exhibits asymptotic freedom, and this is the only good reason why it was proposed as a description of the strong interaction. It explained the experiments, Bjorken scaling, and so forth, that indicated that the quarks are "free" at very short distances. This behavior of quarks - suggestive of free particles - was the only good justification for introducing the non-abelian theory and gluons, and therefore the discovery of asymptotic freedom was essentially identical to the discovery of Quantum Chromodynamics, and this is why these three men got the Nobel prize today.--Lumidek 15:00, 5 Oct 2004 (UTC)
- I'd suspect that the objection is that for QCD to have the property asymptotic freedom QCD must already exist and if it already exists it can't be proposed. While not incorrect, the sentence doesn't communicate the relationship between the two or the significance (i.e. that by having the then unique quality of asymptotic freedom QCD could effectively describe the strong force, which other theories could not do.)

This sentence's poor grammar also makes it hard to understand:
"According to this theory, there is [noun phrase] and that [noun] are [noun phrase]."
The "that" doesn't seem to fit.
