Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I'm trying to calculate an integral which looks unfortunately divergent. The structure is similar to a loop integral but the appendix in the Peskin textbook didn't have a useable form. The integral form is (I did a u substitution to make it easier to look at)

[itex]

\int_x^{\infty}du \frac{u^2}{\omega - u}

[/itex]

Does anyone know of a workable form for this? Introducing a cutoff is possible but I would prefer not to.

Edit: I know that it is divergent. I was hoping for some sort of regularization technique which would allow for a finite answer under certain conditions.

Thank you!
