“…As it turns out, all CP violation in the low energy SUSY vertices is driven by diagonalization of the complex mass matrices of the sfermions, charginos and neutralinos. For more detailed investigations of the diagonalization procedure and extraction of the mass spectrum and CP-violating phases from these mixing matrices we refer the reader to the existing literature, see e.g., [120,126,129,130,131,132,133,134]. Here we only wish to briefly describe the key features of the formulation and the definitions.…”

CP violation in top physics is reviewed. The Standard Model has negligible effects, consequently CP violation searches involving the top quark may constitute the best way to look for physics beyond the Standard Model. Non-standard sources of CP violation due to an extended Higgs sector with and without natural flavor conservation and supersymmetric theories are discussed. Experimental feasibility of detecting CP violation effects in top quark production and decays in high energy e + e − , γγ, µ + µ − , pp and pp colliders are surveyed. Searches for the electric, electro-weak and the chromo-electric dipole moments of the top quark in e + e − → tt and in pp → ttX are descibed. In addition, other mechanisms that appear promising for experiments, e.g., tree-level CP violation in e + e − → tth, ttZ, ttν eνe and in the top decay t → bτ ν τ and CP violation driven by s-channel Higgs exchanges in pp, γγ, µ + µ − → tt etc., are also discussed. * A 2-up version of this postscript file may be obtained at the url

“…In the appendix we present an example for the realization of the required messenger superpotential. 1 In the case of the electron EDM the cancellation between the chargino and neutralino contributions have been shown to occur [9,10,11]. On the other hand, in the case of the neutron EDM it has been known that there are several types of cancellation , that is, the cancellation between the gluino and the chargino exchange diagrams and also the cancellation among the gluino exchange diagrams in themselves etc [9,15].…”

“…The other one is that the soft CP-phases are supposed to be of the order unity by assuming the soft scalar masses to take larger values than 1 TeV, which is considered to be unattractive from the view point of the weak scale supersymmetry. If we can have the third possibility in which the order one CP-phases and the superpartners with the masses of the order of 100 GeV can be consistent with the EDM constraints, it is very interesting and we can have a lot of interesting phenomenology [9,10,11,12,13]. In particular, if we consider the origin of the baryon number asymmetry in the universe, we may need new sources of CP violation.…”

We study phenomenological aspects of the soft supersymmetry breaking parameters in a model with the extended gauge mediation supersymmetry breaking. In this model gaugino masses can be non-universal and as its result physical CP-phases remain in the gaugino sector even after the R-transformation. These phases contribute to the electric dipole moment (EDM) of an electron and a neutron. We show that their experimental bounds can be satisfied even for the situation such that there exist the order one CP-phases and the masses of superpartners are of the order of 100 GeV. *
