HyperPrecision: A Mathematica package for High-Precision Numerical Evaluation of Multivariate Hypergeometric Functions
Sumit Banik, Souvik Bera
In this paper, we present HyperPrecision, a Mathematica package for high-precision numerical evaluation of general Horn-type multivariate hypergeometric functions and their Laurent…
One-loop amplitudes for and productions at the LHC through
Souvik Bera, Colomba Brancaccio, Dhimiter Canko +1
We present analytic expressions for the one-loop QCD helicity amplitudes contributing to top-quark pair production in association with a photon or a jet at the Large Hadron Collide…
Analytic continuations and numerical evaluation of the Appell , , Lauricella and Lauricella-Saran and their Application to Feynman Integrals
Souvik Bera, Tanay Pathak
We present our investigation of the study of two variable hypergeometric series, namely Appell and series, and obtain a comprehensive list of its analytic continuat…
: Algebraic Relations for the Product of Propagators in Feynman integrals
B. Ananthanarayan, Souvik Bera, Tanay Pathak
Motivated by the foundational work of Tarasov, who pointed out that the algebraic relations of the type considered here can lead to functional reduction of Feynman integrals, we su…
