Editing Chirality (physics) (section)

=== More flavors ===
For more  "light" quark species, {{mvar|N}}  [[Flavour (particle physics)|flavors]]  in general, the corresponding chiral symmetries are {{math|U(''N'')<sub>L</sub> × U(''N'')<sub>R′</sub>}},  decomposing into
: <math>\mathrm{SU}(N)_\text{L} \times \mathrm{SU}(N)_\text{R} \times \mathrm{U}(1)_V \times \mathrm{U}(1)_A ~,</math>
and exhibiting a very analogous [[chiral symmetry breaking]] pattern.

Most usually, {{math|1=''N'' = 3}} is taken, the u, d, and s quarks taken to be light (the [[Eightfold way (physics)|eightfold way]]), so then approximately massless for the symmetry to be meaningful to a lowest order, while the other three quarks are sufficiently heavy to barely have a residual chiral symmetry be visible for practical purposes.
