From the table of particles in 'The Particle Explosion' I observe that:(adsbygoogle = window.adsbygoogle || []).push({});

Leptons and quarks have spin 1/2.

Bosons have spin 1.

Mesons, have zero spin; except for quark/antiquark pairs found by electronic detectors, that have spin 1.

Baryons of with more than one type of quark have spin 1/2. Baryons with only one type of quark have spin 3/2.

But the table only lists a small number of particles and I would like to know if there are exceptions to the above observations. (PDG does not come up in a clear readable form on my computer and I cannot find a simple 'table of particle spin').

All the articles on spin, that I have found so far, have one thing in common; very early on, they switch from interpretation and theory to theory only. It is as if, after a certain point, they are unable to explain in words exactly what the numbers mean. Indeed I get the impression that there is no agreed method of explaining spin in a non-mathematical manner. So I would be interested in any article on the subject of spin that includes a non-mathematical explanation (I appreciate that such articles must also include the mathematics).
