Higgs coupling to bottom quarks: SUSY QCD corrections at NNLO — Luminita Mihaila and •Christoph Reißer — Institut für Theoretische Teilchenphysik (TTP), Karlsruhe Institute of Technology (KIT)

The coupling of a neutral Higgs boson in the Minimal Supersymmetric Standard Model to bottom quarks is studied. Using a low energy theorem for Higgs interactions we compute two-loop corrections induced by Quantum Chromodynamics that involve supersymmetric particles. A discussion of the reduced renormalization scale uncertainty and the numerical effects of the results is given.
