Understand

We perform analytical reductions of one-loop tensor integrals with 5 and 6 legs to scalar master integrals.

They are based on the use of recurrence relations connecting integrals in different space-time dimensions.
The reductions are expressed in a compact form in terms of signed minors, and have been implemented in a mathematica package called hexagon.m.
We present several numerical examples.
