Hi guys,
i'm looking at one-loop calculations in terms of helicity spinor (basically a paper by Brandhuber, Travglini and others) language but i have no idea how to integrate them :)
For instance
<br /> \int FeynParam\int d^D L \frac{\langle a|L|b]^2}{(L^2-\Delta^2)^3}<br />
How would I do the loop intergation here?
Cheers,
