NLO QCD corrections to off-shell top-antitop production with semi-leptonic decays at lepton colliders
Ansgar Denner, Mathieu Pellen, Giovanni Pelliccioli
The study of top-quark properties will be a central aspect of the physics programme of any future lepton collider. In this article, we investigate the production of top-quark pairs…
NLO QCD and EW corrections to off-shell production at the LHC
Ansgar Denner, Giovanni Pelliccioli, Christopher Schwan
The production of a single top quark in association with a boson ( production) at the LHC is a relevant probe of the electroweak sector…
Next-to-leading-order electroweak corrections to the production of four charged leptons at the LHC
Benedikt Biedermann, Ansgar Denner, Stefan Dittmaier +2
We present a state-of-the-art calculation of the next-to-leading-order electroweak corrections to ZZ production, including the leptonic decays of the Z bosons into $μ^+μ^-\mathrm{e…
NLO electroweak corrections to off-shell top-antitop production with leptonic decays at the LHC
Ansgar Denner, Mathieu Pellen
For the first time the next-to-leading-order electroweak corrections to the full off-shell production of two top quarks that decay leptonically are presented. This calculation incl…
Irreducible background and interference effects for Higgs-boson production in association with a top-quark pair
Ansgar Denner, Robert Feger, Andreas Scharf
We present an analysis of Higgs-boson production in association with a top-quark pair at the LHC investigating in particular the final state consisting of four b jets, two jets, on…
COLLIER -- A fortran-library for one-loop integrals
Ansgar Denner, Stefan Dittmaier, Lars Hofer
We introduce the fortran-library COLLIER for the numerical evaluation of one-loop scalar and tensor integrals in perturbative relativistic quantum field theories. Important feature…
