How do 6 quarks manifest hiden SU(2) symmetry(together SU(3) symmetry)?

  1. Oct 3, 2011 #1
    Please teach me this:
    It seem to me that lepton manifests broken symmetry SU(2) with couple electron and neutrino(electron is a state with mass,neutrino is a state with nearly zero mass).Similarly for 2 other families of lepton,we have a state with mass and a state with nearly zero mass.But I do not understand how does hiden SU(2) symmetry manifest with 6 quarks,because the hadrons have electro-weak interaction and strong interaction.
    Thank you very much in advance.

    At the moment I know that 6 quarks form 3 ''flavor'' families(example the couple up and down quarks is a ''flavor'' family) that manifest the ''flavor'' symmetry SU(2).Is that correct?
