Quarks can turn into each other, like for instance in the standard beta decay of the neutron where a down quarks decays into an up quark (plus stuff). Thus one might naively ask: why can't a quark decay into an anti-quark, plus stuff? The reason is: baryon number conservation. Only interactions violating baryon number conservation can do that, and none exists within the standard model (except for an unobservable exception noted above). | |
