Hi, Can anyone help with the following integration? Im trying to do it analytically. It looks similar to some integrations I did (a long time ago) in a quantum field theory course, but I cant find it in the standard texts. If you have any advice or recommendations on texts where I could find similar examples worked in detail that would be most helpful. Thanks in advance. --------------------------------------------------------------------------- int dk^3 exp[i k.x]/(k^2(k+q)^2) Here k=(k1,k2,k3), x=(x1,x2,x3), q=(q1,q2,q3), k^2=k1^2+k2^2+k3^2, q is arbitrary, with the usual dot product.
