Idea

In the standard model of particle physics the strange quark is the down-type quark in the second generation of fermions.

Regarded as a heavy quark in 2-flavor chiral perturbation theory, and as a light quark in 3-flavor chiral perturbation theory.

flavors of fundamental fermions in the standard model of particle physics:
generation of fermions	1st generation	2nd generation	3d generation
quarks (qq)
up-type	up quark (uu)	charm quark (cc)	top quark (tt)
down-type	down quark (dd)	strange quark (ss)	bottom quark (bb)
leptons
charged	electron	muon	tauon
neutral	electron neutrino	muon neutrino	tau neutrino
bound states:
mesons	light mesons: pion (udu d) ρ-meson (udu d) ω-meson (udu d) f1-meson a1-meson	strange-mesons: ϕ-meson (ss¯s \bar s), kaon, K*-meson (usu s, dsd s) eta-meson (uu+dd+ssu u + d d + s s) charmed heavy mesons: D-meson (uc u c, dcd c, scs c) J/ψ-meson (cc¯c \bar c)	bottom heavy mesons: B-meson (qbq b) ϒ-meson (bb¯b \bar b)
baryons	nucleons: proton (uud)(u u d) neutron (udd)(u d d)
