Decays of Scalar and Pseudoscalar Higgs Bosons into Fermions: Two-loop QCD Corrections to the Higgs-Quark-Antiquark Amplitude
W. Bernreuther, R. Bonciani, T. Gehrmann +3
As a first step in the aim of arriving at a differential description of neutral Higgs boson decays into heavy quarks, , to second order in the QCD coupling …
