FeynGKZ: a Mathematica package for solving Feynman integrals using GKZ hypergeometric systems

B. Ananthanarayan, Sumit Banik, Souvik Bera +1

In the Lee-Pomeransky representation, Feynman integrals can be identified as a subset of Euler-Mellin integrals, which are known to satisfy Gel'fand-Kapranov-Zelevinsky (GKZ) syste…

Analytic continuations of the Horn $H_{1}$ and $H_{5}$ functions

Souvik Bera, Tanay Pathak

The analytic continuations (ACs) of the double variable Horn $H_{1}$ and $H_{5}$ functions have been derived for the first time using the automated symbolic $Mathematica$ pack…
