Hadrons containing strange valence quarks

Hadrons containing strange valence quarks include the following:

  • down quark.
  • The η and η' flavorless mesons are linear combinations of several quark-antiquark pairs, including the strange-antistrange.
  • The φ flavorless meson is pure strange-antistrange.
  • Strange hyperons: the Σ and Λ have one strange quark, the Ξ two, and the Ω three.
