Description
I report on our recent calculations for Higgs production in weak-boson fusion with subsequent decays of the Higgs boson to bottom quarks. We take into account NNLO QCD corrections to the production and decay and also consider a parton-shower-based description for the Higgs decay. We observe large corrections to fiducial observables in the fixed-order calculation, which we trace back to mainly soft and collinear QCD radiation from the decay. We then show that a parton-shower-based calculation can help to improve the description.
