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.

Review of precision calculations for the measurement of electroweak boson production and properties at hadron colliders [PDF]
Journal of Physics: Conference Series, 2008 We review the present status of precision calculations and tools for the study of single electroweak gauge boson production at hadron colliders. The state-of-the-art of higher-order electroweak and QCD calculations, as well as their combination, is ...

Next-to-leading order electroweak corrections to gg → HH and gg → gH in the large-m t limit
Journal of High Energy Physics, 2023 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
Journal of High Energy PhysicsWhile 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.

Double neutral-current corrections to NLO electroweak leptonic cross sections
Journal of High Energy PhysicsWe 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 ...

Higher-Order Electroweak Contributions to Indirect CP Violation in Neutral Kaons [PDF]
, 2022 The parameter ϵK is an important measure of the imbalance between matter and antimatter in the neutral kaon (K0 and K¯0) system. In particular, ϵK provides a highly sensitive probe of new physics and plays a critical role in the global fit of the Cabibbo-

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.
