That was actually not what I meant at all. What I am saying is that the headline overlooks the significance of the experiment.

As it happens, there have been literally thousands of other measurements of proton/neutron masses and each of those has been a confirmation of the standard model. That by itself is utterly trivial.

If you consult the article, the entire point is that they have confirmed an aspect of quantumchromodynamics. So you'd think that's what the headline would be about.

First, there is no experiment. Second, QCD is the part of the Standard Model that deals with the Strong Force. The headline is accurate.
