  • Classification of particles
    • Hadrons
      • Mesons
        • Pion (0, +1, -1)
        • Kaons (0, +1, -1)
          • have strangeness
        • Made up of quark/anti quark
      • Baryons
        • Nucleons
          • protons (uud)
          • neutrons (udd)
        • Made up of 3 quarks
      • feel the strong interaction
      • Made up of quarks
    • Leptons
      • electron (-1)
        • electron nutino
      • Tau (-1)
        • tau nutrino
      • Muon (-1)
        • muon nutrino
      • do not feel the strong interaction
      • Fundamental particles
      • Neutrinos have 0 charge and almost 0 mass
    • Every particle (even quarks) have a corresponding antiparticle, with the same mass, but opposite charge and a negative particle number
    • Quarks
      • up +2/3
      • Each has a baryon number of +1/3
      • down (-1/3)
      • strange (-1/3)
        • Has a strangeness of -1
      • charm (+2/3)
      • top (+2/3)
      • bottom (-1/3)
