摘要: Abstract We give a detailed presentation of the electroweak one-loop contributions to production mechanisms top quark pairs, q → t and gg , for energy range future hadron colliders. The full gauge-invariant set loop diagrams with Higgs, Z0 W± bosons is considered including strong Yukawa couplings. parton cross sections get sizeable modifications up 40% are sensitive Higgs boson mass coupling. Results also given observable hadronic section pp X where large corrections at level substantially reduced order few percent. For Standard Model maximum contribution about 7% light Mη = 60 GeV. > 200 GeV, typically (2–3)%.
