Beam polarization effects on top-pair production at the ILC. [PDF]
Eur Phys J C Part Fields, 2018 Full one-loop electroweak-corrections for an $e^-e^+\rightarrow t \bar{t}$ process associated with sequential $t\rightarrow b \mu\nu_\mu$ decay are discussed. At the one-loop level, the spin-polarization effects of the initial electron and positron beams

Precision phenomenology with fiducial cross sections in the triple-differential Drell-Yan process
Journal of High Energy Physics, 2023 The production of lepton pairs (Drell-Yan process) at the LHC is being measured to high precision, enabling the extraction of distributions that are triply differential in the di-lepton mass and rapidity as well as in the scattering angle described by ...

Functional reduction of one-loop Feynman integrals with arbitrary masses
Journal of High Energy Physics, 2022 A method of functional reduction for the dimensionally regularized one-loop Feynman integrals with massive propagators is described in detail. The method is based on a repeated application of the functional relations proposed by the author.

Journal of High Energy Physics, 2022 We compute mixed QCD-electroweak corrections to the neutral-current Drell-Yan production of a pair of massless leptons in the high invariant mass region. Our computation is fully differential with respect to the final state particles.

Two-loop tensor integral coefficients in OpenLoops
Journal of High Energy Physics, 2022 We present a new and fully general algorithm for the automated construction of the integrands of two-loop scattering amplitudes. This is achieved through a generalisation of the open-loops method to two loops.

Feynman-diagram evaluation in the electroweak theory with computer algebra [PDF]
, 2001 The evaluation of quantum corrections in the theory of the electroweak and strong interactions via higher-order Feynman diagrams requires complicated and laborious calculations, which however can be structured in a strictly algorithmic way.

Journal of High Energy Physics, 2022 The renormalization of vacuum expectation value parameters, such as v in the Standard Model (SM), is an important ingredient in electroweak renormalization, where this issue is connected to the treatment of tadpoles. Tadpole counterterms can be generated

Computing Techniques for Two-Loop Corrections to Anomalous Magnetic Moments of Leptons [PDF]
, 1996 Two-loop electroweak corrections to the electron, muon, and tau lepton anomalous magnetic moments have been computed recently. Effects of hadronic contributions to the photon propagator in two-loop QED corrections have also been reanalysed.

Two-loop mixed QCD-EW corrections to neutral current Drell-Yan
Journal of High Energy Physics, 2022 We present the two-loop mixed strong-electroweak virtual corrections to the neutral current Drell-Yan process and we provide, as supplementary material, the explicit formulae of the infrared-subtracted finite remainder.
