| Description: | [DPS Seminar] Mr. Souvik Bera (IISc, Bangalore) -- Epsilon Expansion Of Multivariate Hypergeometric Functions In Terms Of Multiple Polylogarithms |
| Date: | Wednesday, Jul 12, 2023 |
| Time: | 3 p.m. - 4:30 p.m. |
| Venue: | Asima Chatterjee Lecture Theatre |
| Details: | Multivariate hypergeometric functions (MHFs) appear as solutions to the dimensionally regularized multiscale Feynman integrals required for higher-order corrections to the scattering amplitude. The Feynman integrals are usually expanded in series in the dimensional regularization parameter. We present the Mathematica package 'MultiHypExp' that allows one to find the series expansion of certain MHFs in terms of multiple polylogarithms. We discuss its algorithm, usage, and application to Feynman integral calculus. |
