Descripción
In high energy hadronic collisions a scalar (or pseudoscalar) Higgs
boson can be efficiently produced via gluon fusion which is mediated
by heavy quark loops. Double (triple) real emission corrections lead
to a Higgs plus two (three)-jets final state, at order alpha_s^4
(alpha_s^5). The 2-jets case is a promising channel to measure the
CP-properties of the Higgs boson with the help of the azimuthal angle
correlation of the two tagging jets, since it is sensitive to the
Higgs-Fermion coupling. A further aspect of interest is the
modification of this correlation by emission of additional jets,
that is, at least by a third jet. We present results for several
differential distributions and show deviations from the broadly used
effective theory which approximates Fermion loops by point-like
interactions.
