One-loop pentagon integral in $d$ dimensions from differential equations in $ε$ -form

Mikhail G. Kozlov, Roman N. Lee

We apply the differential equation technique to the calculation of the one-loop massless diagram with five onshell legs. Using the reduction to $ε$ -form, we manage to obtain a simp…

Introducing SummerTime: a package for high-precision computation of sums appearing in DRA method

Roman N. Lee, Kirill T. Mingulov

We introduce the Mathematica package SummerTime for arbitrary-precision computation of sums appearing in the results of DRA method. So far these results include the following famil…
