Masses
editI just search for those values in 2008's Griffiths and I couldn't find them. He even writes the same value for the u and d quarks. Paranoidhuman (talk) 20:04, 21 November 2016 (UTC)
binding energy
editIs the constituent mass the same as the mass of a "free quark"? If so, isn't 300MeV slightly too light, since nucleons (3 quarks minus binding energy) are ~940 MeV? Cesiumfrog (talk) 01:18, 30 December 2008 (UTC)
quantum chromodynamics binding energy (QCBE)
editFrom quark, section on mass, QCBE link re-directs to QCD article, which doesn't mention QCBE at all. The mass section does give a link to constituent quark. Mabe QCBE could be defined in this article, since it seems to be concerned with how the gluon cloud around valence quarks contributes to the hadron mass, if I am reading correctly. It doesn't seem unreasonable for QCBE to be defined somewhere where the reader can find it from a link. My apologies if it is defined somewhere and I haven't seen it yet.Puzl bustr (talk) 18:18, 9 November 2009 (UTC)
- I was bold and added a binding energy section with my own definition, which is naive and almost certainly wrong, but takes into account quark confinement and the idea that the strong force can pull quark-antiquark pairs out of the vacuum at high energies. By all means replace this with a correct definition, which I was unable to find despite much searching. Also, please do add a reference for the constituent quark masses.Puzl bustr (talk) 06:21, 10 November 2009 (UTC)
