  • All Particles
    • Hadrons
      • Baryons
        • 3 quarks
          • Up down or strange
        • Proton
          • u u d
          • Antiproton
            • u u d
        • Neutron
          • u d d
          • Antineutron
            • u d d
        • other baryons decay into protons eventually
          • via weak interactions
        • baryon number of +1
        • lambda, proton neutron, sigma-minus, sigma-plus, sigma-zero
      • Mesons
        • 2 quarks
          • a quark and an antiquark
        • pi mesons and kaon mesons
          • Kaons
            • k-minus, k-plus, k-zero
              • contains either a strange or anti-strange quark
            • k-zero  mesons have two quark compositions with different strangeness
          • pi
            • pi-minus, pi-plus, pi-zero
            • pi-zero mesons have two different quark compositions
        • kaons decay into pions
    • Fundamental Particles
      • Leptons
        • Electron
          • Electron neutrino
        • Muon
          • Muon neutrino
          • 200 times the mass of the electron
        • Tau
          • Tau neutrino
          • 3500 times the mass of the electron
        • lepton number of +1
        • for each of these six leptons, there is then corresponding anitparticles
        • neutrinos are uncharged and extremely light
        • interact via the strong interaction
        • lepton number of +1
      • Bosons
        • gluons
        • W+ and W-
          • weak nuclear force
          • acts upon all particles
          • makes particles decay like beta plus and minus
          • strangeness doesn't need to be conserved
