Two-loop master integrals for the mixed QCD-electroweak corrections for H → b b ¯ $$ b\overline{b} $$ through a H t t ¯ $$ Ht\overline{t} $$ -coupling
Abstract We present the two-loop master integrals relevant to the O $$ \mathcal{O} $$ (αα s )-corrections to the decay H → b b ¯ $$ b\overline{b} $$ through a H t t ¯ $$ Ht\overline{t} $$ -coupling. We keep the full dependence on the heavy particle masses, but neglect the b-quark mass. The occurring...

The occurring square roots can be rationalised and the result is expressed in terms of multiple polylogarithms. |
