WebIn many cases, higher order corrections have been calculated for inclusive cross sections, but not for fully differential cross sections due to the increased complexity. While inclusive corrections are in good approximation applicable to signal predictions, only fully differential corrections are guaranteed to provide accurate predictions for suppressed backgrounds. Web1 de jul. de 2024 · The production cross section for vector-boson-fusion production, for example, is directly proportional to the square of the coupling strengths between the Higgs boson and W or Z bosons. A modification of these couplings will also affect the rate at which the Higgs boson decays to various final states.
