Numerical integration of loop integrals through local cancellation of threshold singularities
Journal of High Energy Physics, 2022 We propose a new approach that allows for the separate numerical calculation of the real and imaginary parts of finite loop integrals. We find that at one-loop the real part is given by the Loop-Tree Duality integral supplemented with suitable ...

Next-to-leading-order QCD and electroweak corrections to WWW production at proton-proton colliders
Journal of High Energy Physics, 2017 Triple-W-boson production in proton-proton collisions allows for a direct access to the triple and quartic gauge couplings and provides a window to the mechanism of electroweak symmetry breaking. It is an important process to test the Standard Model (SM)

NLO EW and QCD corrections to polarized ZZ production in the four-charged-lepton channel at the LHC
Journal of High Energy Physics, 2021 Measuring the polarization of electroweak bosons at the LHC allows for important tests of the electroweak-symmetry-breaking mechanism that is realized in nature.

Next-to-leading power two-loop soft functions for the Drell-Yan process at threshold
Journal of High Energy Physics, 2021 We calculate the generalized soft functions at O $$ \mathcal{O} $$ ( α s 2 $$ {\alpha}_s^2 $$ ) at next-to-leading power accuracy for the Drell-Yan process at threshold.

Top-Yukawa contributions to bbH production at the LHC
Journal of High Energy Physics, 2019 We study the production of a Higgs boson in association with bottom quarks b b ¯ H $$ \left(b\overline{b}H\right) $$ in hadronic collisions at the LHC, including the different contributions stemming from terms proportional to the top-quark Yukawa ...

One-loop electroweak Sudakov logarithms: a revisitation and automation
Journal of High Energy Physics, 2022 In this work we revisit the algorithm of Denner and Pozzorini for the calculation of one-loop electroweak Sudakov logarithms and we automate it in the MadGraph5_aMC-@NLO framework.

Two-loop amplitudes for Higgs plus jet production involving a modified trilinear Higgs coupling
Journal of High Energy Physics, 2019 We calculate the contributions to the two-loop scattering amplitudes h → gg, h → ggg and h → q q ¯ g $$ h\to q\overline{q}g $$ that arise from a modified trilinear Higgs coupling λ.

Off-shell production of top-antitop pairs in the lepton+jets channel at NLO QCD
Journal of High Energy Physics, 2018 The production of top-quark pairs that subsequently decay hadronically and leptonically (lepton+jets channel) is one of the key processes for the study of top-quark properties at the LHC. In this article, NLO QCD corrections of order Oαs3α4 $$ \mathcal{O}
