On the finite basis topologies for multi-loop high-multiplicity Feynman integrals
Piotr Bargiela, Tong-Zhi Yang
In this work, we systematically analyse Feynman integrals in the `t Hooft-Veltman scheme. We write an explicit reduction resulting from partial fractioning the high-multiplicity in…

Integrated Unitarity for Scattering Amplitudes
Piotr Bargiela
We present a new method for computing multi-loop scattering amplitudes in Quantum Field Theory. It extends the Generalized Unitarity method by constraining not only the integrand o…
