Five legs @ three loops: slightly off-shell dual conformal integrals
Andrei V. Belitsky, Leonid V. Bork, Roman N. Lee +2
We calculate the three-loop master integrals contributing to the three-loop five-point amplitude on the special Coulomb branch of SYM theory. For the genuine pentag…

Method of regions for dual conformal integrals
Leonid V. Bork, Roman N. Lee, Andrei I. Onishchenko
We apply the method of regions to the evaluation of dual conformal integrals with small off-shellness. In contrast to conventional approach, where the separation of regions is perf…
