Two-Loop Threshold Singularities, Unstable Particles and Complex Masses
S. Actis, G. Passarino, C. Sturm +1
The effect of threshold singularities induced by unstable particles on two-loop observables is investigated and it is shown how to cure them working in the complex-mass scheme. The…
NLO Electroweak Corrections to Higgs Boson Production at Hadron Colliders
S. Actis, G. Passarino, C. Sturm +1
Results for the complete NLO electroweak corrections to Standard Model Higgs production via gluon fusion are included in the total cross section for hadronic collisions. Artificial…
Virtual Hadronic and Heavy-Fermion O(alpha^2) Corrections to Bhabha Scattering
Stefano Actis, Michal Czakon, Janusz Gluza +1
Effects of vacuum polarization by hadronic and heavy-fermion insertions were the last unknown two-loop QED corrections to high-energy Bhabha scattering and have been first announce…
Virtual Hadronic Corrections to Massive Bhabha Scattering
Stefano Actis, Janusz Gluza, Tord Riemann
Virtual hadronic contributions to the Bhabha process at the NNLO level are discussed. They are substantial for predictions with per mil accuracy. The studies of heavy fermion and h…
Dominant NNLO corrections to four-fermion production near the W-pair production threshold
S. Actis, M. Beneke, P. Falgari +1
We calculate the parametrically dominant next-to-next-to-leading order corrections to four-fermion production e^- e^+ -> mu^- nubar_mu u dbar + X at centre-of-mass energies near th…
