With unequal up and down quark masses, the neutral pion couples differently to up and down constituent quarks and acquires a tiny coupling to strange quarks, but matching the nucleon hierarchy needs an ad hoc rescaling of mixings.

Symmetry breaking effects in pion couplings to constituent quark currents
With unequal up and down quark masses, the neutral pion couples differently to up and down constituent quarks and acquires a tiny coupling to strange quarks, but matching the nucleon hierarchy needs an ad hoc rescaling of mixings.
