When the quark theory was first proposed, it predicted a new baryon, the omega-minus, to complete a set. It is composed of 3 s quarks.
With the nucleons, containing u and d quarks only, the all-d (delta-) and all-u (delta++) exist only as short-lived 'resonances'. Why is this so, when the all-s omega-minus is directly detectible, e.g in bubble-chambers where it was first seen?
