First, there is no experiment. Second, QCD is the part of the Standard Model that deals with the Strong Force. The headline is accurate.
I have not ever contested the accuracy of the headline. I think I rather implied that it is accurate.
What I am observing, as I have said, is that it does not present the underlying point. An article headline of “Richter meters graph large spikes” would not be a good headline for an article about a massive earthquake in California, however accurate it might otherwise be.
The author who wrote the article would agree with me. He sums the whole thing up as “In other words, QCD is QED,” a statement which is neither equivalent to, nor implied by, the actual headline.
