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.

Next-to-leading order electroweak corrections to gg → HH and gg → gH in the large-m t limit
We compute two-loop electroweak corrections to Higgs boson pair and Higgs plus jet production, taking into account all sectors of the Standard Model. All diagrams with virtual top quarks are computed in an expansion for large top quark mass up to order 1/

Electroweak corrections to τ + τ − production in ultraperipheral heavy-ion collisions at the LHC
While the anomalous magnetic moments of the electron and the muon have been measured with remarkable precision, the magnetic moment of the τ-lepton is only known to rather limited precision.

We present automated next-to-leading order QCD and/or electroweak (EW) predictions for photon-photon processes in ultraperipheral high-energy collisions of protons and ions, extending the capabilities of the MadGraph5_aMC@NLO framework together in ...

Double neutral-current corrections to NLO electroweak leptonic cross sections
We present a method for improving next-to-leading order electroweak (EW) predictions for lepton-scattering processes by consistently including double neutral-current corrections arising from vector-boson-fusion topologies, which are formally of higher ...

Precision phenomenology with fiducial cross sections in the triple-differential Drell-Yan process
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
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.

Two-loop tensor integral coefficients in OpenLoops
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.

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
