Dynamical CP violation in composite Higgs models.
The dynamical origin of the CP violation in electroweak theory is investigated in composite Higgs models. The mechanism of the spontaneous CP violation proposed in other context by Dashen is adopted to construct simple models of the dynamical CP violation. Within the models the size of the neutron electric dipole moment is estimated and the constraint on the ε-parameter in K-meson decays is dis...
متن کاملHiggs Physics and Cp Violation
The CP violation in K and B decays are discussed with the emphasize on the precise prediction for ǫ ′ /ǫ and the new physics effects from a class of models with additional Higgs doublets and fermions. The contributions from standard model with two-Higgs-doublet (S2HDM) to K, B mixing and decays are briefly reviewed. The possible large effects on CP violation in B → φK is discussed in an extende...
متن کاملCp Symmetry Violation
The symmetry known as CP is a fundamental relation between matter and antimatter. The discovery of its violation by Christenson, Cronin, Fitch, and Turlay (1964) has given us important insights into the structure of particle interactions and into why the Universe appears to contain more matter than antimatter. In 1928, Paul Dirac predicted that every particle has a corresponding antiparticle. I...

We discuss the feasibility of spontaneous CP violation being induced by radiative corrections in 2HDM’s. Specifically, we analyze the cases of gaugino/higgsino effect on MSSM, and a new model with an extra exotic quark doublet. The new model, while demonstrating well the Georgi-Pais theorem, is also expected to be phenomenlogically interesting. ————— ⋆ Talk given by O.K. at MRST conference, McG...
متن کاملCP 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.
