Mixed QCD-EW corrections for Higgs leptonic decay via HW + W − vertex
Journal of High Energy Physics, 2021 We consider the two-loop corrections to the HW + W − vertex at order αα s . We construct a canonical basis for the two-loop integrals using the Baikov representation and the intersection theory.

Automation of NLO QCD and EW corrections with Sherpa and Recola [PDF]
, 2017 This publication presents the combination of the one-loop matrix-element generator Recola with the multipurpose Monte Carlo program Sherpa. Since both programs are highly automated, the resulting Sherpa+Recola framework allows for the computation of -in ...

Journal of High Energy Physics, 2022 We consider the problem of obtaining higher order in regularization parameter ε analytical results for master integrals with elliptics. The two commonly employed methods are provided by the use of differential equations and direct integration of ...

Evaluating multi-loop Feynman integrals numerically through differential equations
Journal of High Energy Physics, 2019 The computation of Feynman integrals is often the bottleneck of multi-loop calculations. We propose and implement a new method to efficiently evaluate such integrals in the physical region through the numerical integration of a suitable set of ...

The BlackHat Library for One-Loop Amplitudes [PDF]
, 2013 We present recent next-to-leading order (NLO) results in perturbative QCD obtained using the BlackHat software library. We discuss the use of n-tuples to separate the lengthy matrix-element computations from the analysis process.

QCD static force in gradient flow
Journal of High Energy Physics, 2022 We compute the QCD static force and potential using gradient flow at next-to-leading order in the strong coupling. The static force is the spatial derivative of the static potential: it encodes the QCD interaction at both short and long distances.
