Mixed QCD-electroweak corrections to Higgs boson production in gluon fusion
Charalampos Anastasiou, Radja Boughezal, Frank Petriello
We compute the 3-loop O(αα_s) correction to the Higgs boson production cross section arising from light quarks using an effective theory approach. Our calculation probes the factor…
The one-loop gluon amplitude for heavy-quark production at NNLO
Charalampos Anastasiou, S. Mert Aybat
We compute the one-loop QCD amplitude for the process gg-->Q\bar{Q} in dimensional regularization through order ε^2 in the dimensional regulator and for arbitrary quark mass values…
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…
