In this talk I begin with some general discussion of the history of CP violation, then move on to aspects of the aspon model including the production of new particles at LHC, implications for B decay, generalized Cabibbo mixing and a reevaluation of kaon CP violation. Finally there is a summary.

CP violation in supersymmetric models is reviewd with focus on explicit CP violation in the MSSM. The topics covered in particular are CP-mixing in the Higgs sector and its measurement at the LHC, CP-odd observables in the gaugino sector at the ILC, EDM constraints, and the neutralino relic density.

It is well known that supersymmetry (SUSY) gives neutron and electron electric dipole moments (dn and de) which are too large by about 10 . If we assume a SUSY model cannot contain fine-tunings or large mass scales, then one must require that the SUSY breaking mechanism give real soft breaking parameters, in which case the minimal SUSY model has no CP violation other than from the CKM matrix (b...

Some past, present, and future aspects of CP violation are reviewed. The discrete symmetries C, P, and T are introduced with an example drawn from Maxwell’s Equations. The history of the discovery of CP violation in the kaon system is described briefly, and brought up-to-date with a review of recent results on kaon decays. The candidate theory of CP violation, based on phases in the Cabibbo-Kob...

We investigate the effect on the sphaleron in the two Higgs doublet electroweak theory of including CP violation in the Higgs potential. To have better control over the relation between the sphaleron energy and the physical quantities in the theory, we show how to parametrize the Higgs potential in terms of physical masses and mixing angles, one of which causes CP violation. By altering this CP...

The CKM mechanism is well established as the dominant mechanism for CP violation, which was first discovered in the neutral kaons in 1964 [1]. To search for new sources of CP violation, one can exploit a handful of systems in which the standard model makes a precise prediction of CP violation. In the B s → J/ψφ system, CP violation in the interference of mixing and decay is precisely predicted ...

Di erences in the behaviour of matter and antimatter have been observed in K and B meson decays, but not yet in any baryon decay. Such di erences are associatedwith the non-invariance of fundamental interactions under the combined chargeconjugation and parity transformations, known as CP violation. Here, using data from the LHCb experiment at the LargeHadron Collider, we search for CP-violating...

We study Higgs boson decays in the minimal supersymmetric standard model where the tree–level CP invariance of the Higgs potential is explicitly broken by loop effects of soft CP–violating Yukawa interactions related to scalar quarks of the third generation. The scalar–pseudoscalar mixing among two neutral CP–even Higgs bosons and one CP–odd Higgs boson due to explicit CP violation modifies the...

It is shown that the mechanism of spontaneous symmetry breaking provides not only a mechanism for giving mass to the bosons and the fermions, but also a mechanism for generating CP-phase of the bosons and the fermions. A two-Higgs doublet model with Vacuum CP Violation and Approximate Global U(1) Family Symmetries (AGUFS) is built and may provide one of the simplest and attractive models in und...
