CP Violation in Higgs Decays
We study CP violation in fermion pair decays of Higgs boson. We identify some CP odd observables related to the tree level decay amplitude. We find that a few thousand Higgs boson decay events can already provide important information about CP violation. If the Higgs boson is produced, such an analysis could be carried out at the SSC, LHC and NLC.
متن کاملCP violation in charged Higgs boson decays in the MSSM
CP violation in H± decays into the three possible decay modes into ordinary particles, 1) H± → tb, 2) H± → ντ and 3) H± → W±h0 is considered. Analytic expressions and numerical results for the CP violating decay rate asymmetries in the MSSM are obtained. Increasing tanβ the asymmetries for the fermionic decays, H± → tb and H± → ντ , decrease and it increases for H± →W±h0. The asymmetry of H± → ...

متن کاملCp Violation in Higgs Decays Due to Majorana Neutrinos
The possibility of observing CP violation in the decays of Higgs particles into top-quark, W and Z-boson pairs induced by heavy Majorana neutrinos is discussed. In the context of minimal “see-saw” models with interfamily mixings, we find that Majorana neutrinos may give rise to sizable CP -odd effects at the one-loop electroweak order. We present numerical estimates of typical CP -odd observabl...
متن کاملProbing CP Violation Via Higgs Decays to Four Leptons
Since decays to four leptons is widely considered a promising way to search for the Higgs particle, we show how the same final state can also be used to search for signals of CP nonconservation. Energy asymmetries and triple correlations are related to parameters in the underlying CP violating effective interaction at the H-W -W and H-Z-Z vertex. Expected size of the effects are shown to be sma...
