Higgs production via gluon fusion in association with two or three jets in supersymmetric models

Within the MSSM neutral Higgs bosons can be efficiently produced via gluon fusion in high energy hadronic collisions. Real emission corrections to Higgs production can lead to a Higgs plus two- and three-jet final state. This thesis presents the calculation of scattering amplitudes, as induced by triangle-, box-, pentagon- and hexagon-loop diagrams. Finally, resulting hadronic cross sections are discussed and phenomenologically relevant distributions for the LHC are shown.
