Two-loop integrals for production at hadron colliders in the leading-colour approximation

Souvik Bera, Colomba Brancaccio, Dhimiter Canko +2

We complete the calculation of the two-loop Feynman integrals required for the next-to-next-to-leading order QCD corrections to on-shell top--antitop production in association with…

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…

: 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…
