I Sunset 2-loops diagram

  1. Oct 20, 2016 #1
    Hi all,

    I'd like to calculate the self energy amplitude of the following sunset diagram (take the middle for instance ) Untitled.png

    can any one help me in distributing the momentum on the internal propagators ?

    Best

    Isn't this perhaps a homework problem? How far are you in thinking about it?
