Our wall as the origin of CP violation

چکیده

A possibility that the origin of the CP violation in our world is a domain wall itself, on which we are living, is investigated in the context of the brane world scenario. We estimate the amount of the CP violation on our wall, and show that either of order one or suppressed CP phases can be realized. An interesting case where CP is violated due to the coexistence of the walls, which conserve CP individually, is also considered. We also propose a useful approximation for the estimation of the CP violation in the double-wall background. e-mail address: [email protected]

CP violation due to the existence of other wall

A possibility that the CP violation in our world is caused by the existence of other wall without any messenger bulk fields is investigated in the context of the brane world scenario. We estimate the amount of the CP violation on our wall, and find that it becomes exponentially small as the distance between the walls increases. An interesting case where CP is violated due to the coexistence of ...

Electric dipole moments from spontaneous CP violation in SU(3)-flavoured SUSY

The SUSY flavour problem is deeply related to the origin of flavour and hence to the origin of the SM Yukawa couplings themselves. Since all CP-violation in the SM is restricted to the flavour sector, it is possible that the SUSY CP problem is related to the origin of flavour as well. In this work, we present three variations of an SU(3) flavour model with spontaneous CP violation. Such models ...

(Dated: April 8, 2008) We reconsider the origin of CP violation in fundamental theory. Existing string models of spontaneous CP violation make ambiguous predictions, due to the arbitrariness of CP transformation and the apparent non-invariance of the results under duality. We find an unambiguous modular CP invariance condition, applicable to predictive models of spontaneous CP violation, which ...

CP Violation and Rare Decays

The origin of CP violation is one of the fundamental questions of particle physics. Currently, we know of only two distinct examples of CP violation: the matter-antimatter asymmetry in the universe and CP violation in the neutral kaon system. Although there are several manifestations of CP violation in the neutral kaon system, all of them (with the possible exception of the measurements of = wh...

A Model for the Origin and Mechanisms of Cp Violation

In this talk I will show that the two-Higgs doublet model with vacuum CP violation and approximate global U(1) family symmetries may provide one of the simplest and most attractive models for understanding the origin and mechanisms of CP violation. It is shown that the mechanism of spontaneous symmetry breaking provides not only a mechanism for generating masses of the bosons and fermions, but ...
