  • particles
    • are they affected by the strong force?
      • yes-Hadrons
        • baryons
          • heavier than mesons
          • protons and neutrons
            • not primary matter
            • protons (u+u+d)
              • 2/3 +2/3 -1/3 =1 electron charge
              • anti protons (-u-u-d)
            • neutrons (d+d+u)
              • -1/3 -1/3 +2/3 +0 electron charge
              • anti neutrons (-d-d-u)
          • antibaryons
            • made of 3 anti quarks
          • made of 3 quarks
          • if unstable change into a stable proton
        • heaver than Leptons
      • no- Leptons
        • electron leptons
          • electrons +electron nutrenos
            • neutrinos interact very little
              • travel almost as fast as light
        • lighter than Hadrons
        • leptons and antileptons can interact to produce Hardons
  • charge of -1/3 electron charge
