AbstractAbstract
[en] In this work we calculated observables which can be used to determine the CP parity of the Higgs boson. We considered the neutral Higgs bosons of the MSSM as well as CP-indefinite Higgs bosons. The calculation have been made for an application at LHC. For Higgs production we considered gluon fusion (in NLO) and b-quark annihilation (in LO) and for the Higgs decay studied the decay in tau lepton or top quark. We find that the angle between the charged particles of the tau (or top) decay are a good observable to determine CP properties of the intermediate Higgs bosons. For CP indefinite Higgs bosons we considered triplet-correlation-observables. (orig.)
