Abstract
We discuss how correlations among momenta of the decay products may yield information about the CP-parity of the Higgs particle. These are correlations of decay planes defined by the momenta of pairs of particles as well as correlations between energy differences. Our study includes finite-width effects. In the narrow-width approximation the angular correlations coincide with previously reported results. The correlations between energy differences turn out to be a much better probe for CP determination than the previously suggested angular correlations, especially for massive Higgs bosons.
