Symmetries

• Continuous Symmetries
• space-time translation
• rotational invariance
• Lorentz boosts
• gauge invariance
• Noethers Theorem continuous symmetries
  correspond to conserved quantities
• energy-momentum
• angular momentum
• center-of-momentum
• electric charge

• Discrete Symmetries
• parity P x ? -x
• time T t ? -t
• charge C q ? -q
• particle P12 x1 ? x2 exchange
• Discrete Theorems
• spin-statistics theorem
• CPT theorem
