A bstract We present the two-loop master integrals relevant to the O $$ mathcal{O} $$ ( αα ~( s ))-corrections to the decay H → b b ˉ $$ boverline{b} $$ through a H t t ˉ $$ Htoverline{t} $$ -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.
