B ¯ B Mixing and CP Violation in SU(2)L × SU(2)R × U(1) Models
نویسنده
چکیده
We reexamine the mass mixing and CP violation in the B ¯ B system in general SU(2) L × SU(2) R × U(1) models related to the recent measurements. The right-handed contributions can be sizable in B ¯ B mixing and CP asymmetry in B decays for a heavy W ′ even with a mass about 3 TeV. On the other hand the lower bound on the mass of W ′ can be taken down to approximately 300 GeV.

Updates of WR effects on CP angles determination in B decays
The recently observed CP violation in B decay and B-B mixing data put constraints on the mass of WR and the parameters of the right-handed current quark mixing matrix V R in SU(2)L × SU(2)R × U(1) gauge model. It is shown that the allowed region of parameters are severely restricted for light WR with mass on the order of 1 TeV. There exist sets of parameters which can accommodate large CP viola...
متن کاملAnatomy of Mixing-Induced CP Asymmetries in Left-Right-Symmetric Models with Spontaneous CP Violation
We investigate the pattern of CP violation in K–K̄0, B d–B̄ 0 d and B 0 s–B̄ 0 s mixing in a symmetrical SU(2)L×SU(2)R×U(1) model with spontaneous CP violation. We calculate the phases of the left and right quark mixing matrices beyond the small phase approximation and perform a careful analysis of all relevant restrictions on the model’s parameters from ∆mK , ∆mB , ǫ, ǫ/ǫ and the CP asymmetry in ...

متن کاملAutomatic CP Invariance and Flavor Symmetry
The approximate conservation of CP can be naturally understood if it arises as an automatic symmetry of the renormalizable Lagrangian. We present a specific realistic example with this feature. In this example, the global Peccei-Quinn symmetry and gauge symmetries of the model make the renormalizable Lagrangian CP invariant but allow non zero hierarchical masses and mixing among the three gener...
متن کاملEnhancement of ǫ ′ / ǫ in the SU ( 2 ) L × SU ( 2 ) R × U ( 1 ) model
We explore the possible enhancement of direct CP violating parameter ǫ/ǫ in the general left-right model based on the SU(2)L×SU(2)R×U(1) gauge group. The mixing matrix of right-handed quarks, V R CKM is observable in the left-right model, and provides new source of CP violating phase. We calculate the parameter ǫ/ǫ in the left-right model and show that the new phases can yield the sizable contr...
