Flavor Dependence and Mass Hierarchy
Quark masses exhibit a dramatic hierarchy, spanning several orders of magnitude. The masses of the first generation (up quark (flavor)/) and down quark (flavor)/)) are exceedingly small, often referred to as "chiral limit" masses, while the top quark mass approaches the scale of the weak boson masses.
