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…
Anomalous Threshold as the Pivot of Feynman Amplitudes
S. Goria, G. Passarino
Reduction techniques, Landau singularities and differential equations for Feynman amplitudes are briefly reviewed.
Complete Two-Loop Corrections to H -> gamma gamma
Giampiero Passarino, Christian Sturm, Sandro Uccirati
In this paper the complete two-loop corrections to the Higgs-boson decay, H -> gamma gamma, are presented. The evaluations of both QCD and electroweak corrections are based on a nu…
Two-Loop Renormalization in the Standard Model Part III: Renormalization Equations and their Solutions
S. Actis, G. Passarino
In part I and II of this series of papers all elements have been introduced to extend, to two loops, the set of renormalization procedures which are needed in describing the proper…
Two-Loop Renormalization in the Standard Model Part II: Renormalization Procedures and Computational Techniques
S. Actis, G. Passarino
In part I general aspects of the renormalization of a spontaneously broken gauge theory have been introduced. Here, in part II, two-loop renormalization is introduced and discussed…
