Abstract: In high energy hadronic collisions a scalar or pseudoscalar Higgs boson,Phi=H,A, can be efficiently produced via gluon fusion, which is mediated byheavy quark loops. We here consider double real emission corrections to Phi=Aproduction, which lead to a Higgs plus two-jet final state, at order alpha s^4.Full quark mass effects are considered in the calculation of scatteringamplitudes for the CP-odd Higgs boson A, as induced by quark triangle-, box-and pentagon-diagrams. They complement the analogous results for a CP-evenHiggs boson H in Ref.1. Interference effects between loops with top andbottom quarks as well as between CP-even and CP-odd couplings of the heavyquarks are fully taken into account.
