 P: 282 What is the gyromagnetic ratio of quarks and gluons ? Does the ratio differs between antiquarks and quarks ?
 Sci Advisor HW Helper PF Gold P: 2,024 Gluons have no magnetic moment, so the gyromangetic ratio is zero. The gyromagnetic mooment of quarks depends on the model of a quark, which is still open for speculation. For point, Dirac-like quarks the gyromagnetic ratio would equal 2, with the same type of small correction like that for an electron or muon. If quarks have a different anomalous moment (like protons do), then the GR depends on the particular model.

By the same token, Z boson and neutrino has GR = 0 since it's neutral, right ?

 P: 455 Gyromagnetic Ratio Not because they are neutral, but because they have no mag moment. The neutron is neutral, but has a mag moment and a GR.
 P: 21 To see whether they would have the same or different gyromagnetic ration, you need to see if they obey the same or different symmetries.
