Signals of Higgs sectorCPviolation in neutral Higgs boson decays

Two-Higgs-doublet electroweak models with soft CP violation in the Higgs sector underpin many current models for baryogenesis at the electroweak scale and give rise to CP-violating couplings between neutral Higgs bosons and fermions. The implications of these couplings on the neutral Higgs boson decay channels H\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\gamma}, H\ensuremath{\rightarrow}tt\ifmmode\bar\else\textasciimacron\fi{}\ensuremath{\rightarrow}${\mathit{W}}^{+}$${\mathit{bW}}^{\mathrm{\ensuremath{-}}}$ b\ifmmode\bar\else\textasciimacron\fi{}, and H\ensuremath{\rightarrow}ZZ\ensuremath{\rightarrow}${\mathit{l}}_{1}$l${\mathrm{\ifmmode\bar\else\textasciimacron\fi{}}}_{1}$${\mathit{l}}_{2}$l${\mathrm{\ifmmode\bar\else\textasciimacron\fi{}}}_{2}$ are investigated with particular emphasis on the angular correlations expected between the final state particles.
