The two-loop QCD amplitude gg -> h,H in the Minimal Supersymmetric Standard Model
Charalampos Anastasiou, Stefan Beerli, Alejandro Daleo
We present the two-loop QCD amplitude for the interaction of two gluons and a CP-even Higgs boson in the Minimal Supersymmetric Standard Model. We apply a novel numerical method fo…
Evaluating multi-loop Feynman diagrams with infrared and threshold singularities numerically
Charalampos Anastasiou, Stefan Beerli, Alejandro Daleo
We present a method to evaluate numerically Feynman diagrams directly from their Feynman parameters representation. We first disentangle overlapping singularities using sector deco…
Two-loop amplitudes and master integrals for the production of a Higgs boson via a massive quark and a scalar-quark loop
Charalampos Anastasiou, Stefan Beerli, Stefan Bucherer +2
We compute all two-loop master integrals which are required for the evaluation of next-to-leading order QCD corrections in Higgs boson production via gluon fusion. Many two-loop am…
