Chapter 6
Some basic concepts of theoretical particle physics

We now come to the first hard part of the class. We’ll try to learn what insights we can gain from the equation governing relativistic quantum mechanics.

 6.1 The difference between relativistic and NR QM
 6.2 Antiparticles
 6.3 QED: photon couples to e+e
 6.4 Fluctuations of the vacuum
  6.4.1 Feynman diagrams
 6.5 Infinities and renormalisation
 6.6 The predictive power of QED
 6.7 Problems
