Invariant formulation of CP violation for four quark families
We find a minimal set of constraints which are independent of the choice of weak quark basis and necessary and sufficient for CP conservation for four quark families, including also the case of degenerate quark masses. These invariant conditions are written in the mass eigenstate basis as a function of the fermion masses and charged current mixings. CP violation is then related to the areas of ...
متن کاملCp Violation
Three possibilities for the origin of CP violation are discussed: (1) the Standard Model in which all CP violation is due to one parameter in the CKM matrix, (2) the superweak model in which all CP violation is due to new physics and (3) the Standard Model plus new physics. A major goal of B physics is to distinguish these possibilities. CP violation implies time reversal violation (TRV) but di...
متن کاملCp Violation*
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.
متن کاملNew Constraint on Weak CP Phase Rephasing Invariant and Maximal CP Violation
By using the relation between CP-violation phase and the mixing angles in CabibboKobayashi-Maskawa matrix postulated by us before, the rephasing invariant is recalculated. Furthermore, the problem about maximal CP violation is discussed. We find that the maximal value of Jarlskog’s invariant is about 0.038. And it presents at α ≃ 71.00, β ≃ 90.20 and γ ≃ 18.80 in triangle db. PACS number(s): 11...
متن کاملCP Violation
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...
