If you have an integral you can't solve, but think that someone else in the workshop might, try adding it on this page. Likewise, if you see an integral on this page which you know how to solve, write in the answer (or the procedure for solving it.) If you need help in adding math to a wikipage take a look at Math Mode on the practice page.

1) The hard integral
The integral below (the "hard" integral topology) appears in the two-loop expansion of the lightlike polygonal Wilson loop at weak coupling (see for example Equation (B.1) of this paper). It would be very interesting to have its analytic expression for generic values of the kinematic invariants. Here it is:

where

and

The numerator is given by

The momenta

are lightlike, whereas in the most general configuration
