QCD Corrections to Associated Higgs Boson Production

الأصل · EN

We compute QCD corrections to the processes e+e-→ t t h⁰ and pp→ t t h⁰ by treating the Higgs boson as a parton which radiates off a heavy quark. This approximatiion is valid in the limits Mₕ<<Mₜ and Mₕ, Mₜ<<√s. The corrections increase the rate for pp→ t t h⁰ at the LHC by a factor of 1.2 to 1.5 over the lowest order rate for an intermediate mass Higgs boson, Mₕ < 180 GeV. The QCD corrections are small for e+e-→ t t h⁰ at √s=1 TeV.
