Contribution of heavy fermions to the mechanism of Higgs boson production

Resumo

Heavy quarks of mass much greater than the Higgs boson (H) mass have virtually no effect on the cross section for Higgs boson production at the Large Hadron Collider (LHC). A mechanism that is responsible for the appearance of the respective small factors is presented, and their meaning is clarified. It appears that they precisely correspond to a simple quantum-mechanical picture of the H-production process.
