Lecture quizzes
Quiz 1
(page 274)
Conside a scalar field theory, where the Lagrangian includes an interaction term \[V_I = \frac{\lambda}{4!} \phi^4 + \frac{\bar \lambda}{3!}\phi^3\]
Draw two possible diagrams for the \(\phi \phi \to \phi \phi \phi\) scattering. Indicate how the scattering amplitudes depend on \(\lambda\) and \(\bar \lambda\) (write e.g. \(\lambda^2 \bar \lambda\)). Remember to click Save.
Quiz 2
(page 277)
QED intro. Check that you understand what we are doing
Quiz 3
Consider the pair annihilation \(e^+ + e^- \to \gamma + \gamma\). You do not need to draw fermion or momentum arrows here.
