Quarks & Leptons

Quarks & Leptons

1. Particles

   • Hadrons
     • Baryrons
       • Protons
       • Neutrons
     • Mesons
       • Pions
       • Kaons
   • Leptons
     • Electrons
     • Muon

2. Leptons at work

   • Leptons can collide to form hadrons
   • Change through weak interaction

3. Strangeness

   • React in a different way

4. Quarks

   • up, down, strange
     • anti-up, anti-down, anti-strange
   • Baryons consist of 3 quarks
     • Protons- uud
     • Neutron udd
   • Mesons consist of 2 quarks- a quark and anti quark
   • Beta minus Decay

5. Conservation Rules

   • Conservation of energy
   • Conservation of Baryon Number
   • Conservation of Lepton number
   • Conservation of strangeness
