I review several topics involving CP violation with heavy hadrons. In particular, I discuss (i) Hyperons: CP violation in the decay Λ → pπ, (ii) Charm: indirect CP violation in the D system, both within and beyond the SM, and (iii) Beauty: indirect CP violation in the neutral B-meson system beyond the SM.

Predictions for CP violation in the three generation Standard Model are reviewed based on what is known about the Cabibbo-Kobayashi-Maskawa matrix. Application to the I(and B meson systems are emphasized.

We study the possibility to test CP invariance in the W + W − production via photon fusion at NLC. The predictions of the CP violation effects are made within two Higgs doublet extensions of the minimal standard model, where CP violation is introduced by a neutral Higgs exchange in s channel in our case. The width effect in the Higgs propagator on the CP violation effects is studied in detail. ...

Several pieces of direct and indirect evidence now suggest that the KobayashiMaskawa mechanism plays a distinguished role for CP violation at the electroweak scale. This talk provides a general overview of CP violation in its various contexts, emphasizing CP violation in flavour-violating interactions, such as due to the Kobayashi-Maskawa mechanism. I then review a few recent theoretical develo...

Abstract We study CP violation in a multi-Higgs doublet model based on a S3 × Z3 horizontal symmetry. We consider two mechanisms for CP violation in this model: a) CP violation due to complex Yukawa couplings; and b) CP violation due to scalar-pseudoscalar mixings. We find that the predictions for ǫ/ǫ, CP violation in B decays and the electric dipole moments of neutron and electron are differen...

The decay KL → π0e+e− is being searched for as a signal of direct ∆S = 1 CP violation. We provide a thorough updating of the analysis of the three components of the decay: 1) Direct CP violation, 2) CP violation through the mass matrix and 3) CPconserving (two-photon) contributions. First the chiral calculation of the KS → π0e+e− rate, due to Ecker, Pich and de Rafael (EPR), is updated to inclu...
