摘要：

We present the two-loop master integrals relevant to the O((s))-corrections to the decay H bb-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.
