The package TopoID and its applications to Higgs physics
Jens Hoff (DESY)

I explain the main techniques behind the {tt Mathematica} package {tt TopoID} which aims at automation of multiloop calculations. One application is the N\(^3\)LO Higgs boson cross section for which we recently completed the calculation of the contribution from the \(qq^\prime\)-channel. As another application we considered the cross section for Higgs boson pairs at NLO and at NNLO in the soft-virtual approximation including effects of the top quark mass.
