AS level particle physics AQA

1. Quarks

   • Hadrons
     • Baryons
       • Made form 3 quarks. Has a baryon number of 1 and no strangness.
       • Neutron - UDD
       • Proton - UUD
       • The proton is the only stable baryon
     • Mesons
       • Table
       • only the kaons can interact by the strong and weak interaction where the strangness is not conserved
     • interact via the strong interaction
   • Table

2. Interactions

   • Alpha decay
   • Beta- decay
   • Beta + decay
   • Pair production

3. Interactions

   • Gravitiy
   • Electromagnet
   • STrong
   • Weak
