" ... In particle physics, there are six fundamentally different types of quarks in the Standard Model: the up, down, strange, charm, bottom, and top quarks. The six types, known as flavors, are presented in order from lowest to greatest mass. Whenever you create one of the four most massive types of quarks, they’ll rapidly (in ~10-24 seconds or so) hadronize: become bound into either baryons (combinations of three quarks) or mesons (quark-antiquark pairs). Whatever composite particle arises will then inevitably decay through the weak interaction into a set of particles where that heavy quark has transformed into lighter quark. ... "
