Fundamental Particles

Fundamental Particles

1. Fundamental particles

   • Quarks
     • Up
       • Q=+2/3
       • B=+1/3
     • Down
       • Q=-1/3
       • B=+1/3
     • Strange
     • Charm
     • Top
     • Bottom
   • Leptons
     • Electron
     • Electron neutrino
     • Muon
     • Muon neutrino
     • Tau
     • Tau neutrino
   • Particles that cannot be broken down by other consistents. Protons and nuetrons are made up from qauarks therefore nuecleons are not fundamental particles
     • Protons
       • up,up,down (uud)
     • Neutrons
       • up,down,down (udd)

2. Hadrons

   • Particles affected by the strong force, eg Protons and Neutrons
   • Types
     • Bayrons
       • Protons and Neutrons
         • B=1
       • Made from 3 Quarks
     • Mesons
       • Pions and Kaons
         • B=0
       • Made from 1 Quark and 1 Antiquark

3. Antiparticles

   • Quarks
     • Anti-Up
     • Anti-Strange
     • Anti-Bottom
     • Anti-Down
     • Anti-Charm
     • Anti-Top
   • Leptons
     • Positron
     • Anti Electron-neutrino
     • Anti-Muon
     • Anti-Tau
     • Anti Muon-neutrino
     • Anti Tau-neutrino

4. Terminology

   • Bayron number
     • Number of bayrons in the reaction
   • Lepton number
     • Number of leptons in the reaction
