Abstract
We present the two-loop master integrals relevant to the \( \mathcal{O} \)(ααs)-corrections to the decay H → \( b\overline{b} \) through a \( Ht\overline{t} \)-coupling. We keep the full dependence on the heavy particle masses, but neglect the b-quark mass. The occurring square roots can be rationalised and the result is expressed in terms of multiple polylogarithms.
