 In particular, the computed mass must be small, .For three light quarks, the up quark, down quark, and strange quark, the flavor-chiral symmetries extending those discussed above also decompose, to Gell-Mann's 

The chiral symmetry generators spontaneously broken comprise the coset space formula_7.This space is not a group, and consists of the eight axial generators, corresponding to the eight light pseudoscalar mesons, the nondiagonal part of formula_8.
