Looking for simple self energy calculations

  1. Jul 19, 2010 #1
    Hi everybody,

    I'm writing my QFT exam tomorrow and I know that there will be a self energy calculation. Since I am not that familiar with it, because we didn't do any self energy calculations in the exercises so far, I would like to do some simple calculations.
    I think the electron self energy, the vacuum polarization and the vertex correction are too difficult for an exam. I already found the easiest example for Phi^3 theory and I think something like this could come in the exam:

    -----( )---------- (1 Bubble)

    The calculation was not too difficult.
    Do you guys know any other simple selfenergy calculation? I would like to be prepared as good as possible for tomorrow :)
    Thank you!
