Abstract We investigate the pattern of CP violation in K0– K 0 , B0d– B 0 d and B0s– B 0 s mixing in a symmetrical SU(2)L×SU(2)R×U(1) model with spontaneous CP violation. From a set of fixed quark masses and mixings, 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 ΔmK, ΔmB, ϵ, ϵ′/ϵ and the CP asymmetry aCP in B0d→J/ψK0S. Of 64 possible sets of… 
General CP violation in minimal left–right symmetric model and constraints on the right-handed scale
Abstract In minimal left–right symmetric theories, the requirement of parity invariance allows only one complex phase in the Higgs potential and one in the Yukawa couplings, leading to a two-phase
Two Higgs bi-doublet left-right model with spontaneous P and CP violation
A left-right symmetric model with two Higgs bi-doublet is shown to be a consistent model for both spontaneous P and CP violation. The flavor changing neutral currents can be suppressed by the
Viability of minimal left-right models with discrete symmetries
We provide a systematic study of minimal left-right models that are invariant under P, C, and/or CF transformations. Due to the high amount of symmetry such models are quite predictive in the amount

A bstractWe present a complete study of ΔS = 2 and ΔB = 2 processes in the left-right model (LRM) based on the weak gauge group SU(2)L × SU(2)R × U(1)B−L. This includes εK, ΔMK, ΔMq, $
Dark Matter and Collider Studies in the Left-Right Symmetric Model with Vector-Like Leptons
In the context of a left-right symmetric model, we introduce one full generation of vector-like lepton doublets (both left and right-handed) together with their mirror doublets. We show that the
Neutrinos in a left-right model with a horizontal symmetry
We analyze the lepton sector of a left-right model based on the gauge group SU(2){sub L}xSU(2){sub R}xU(1), concentrating mainly on neutrino properties. Using the seesaw mechanism and a horizontal
Two Higgs bidoublet model with spontaneous P and CP violation and decoupling limit to the two Higgs doublet model
The two Higgs bidoublet left-right symmetric model (2HBDM) as a simple extension of the minimal left-right symmetric model with a single Higgs bidoublet is motivated to realize both spontaneous
Left-Right Symmetric Model without Higgs Triplets
We develop a minimal left-right symmetric model based on the gauge group SU(3)C⊗SU(2)L⊗SU(2)R⊗U(1)B−L wherein the Higgs triplets conventionally employed for symmetry breaking are replaced by Higgs
UbiquitousCPviolation in a top-inspired left-right model
We explore CP violation in a Left-Right Model that reproduces the quark mass and CKM rotation angle hierarchies in a relatively natural way by fixing the bidoublet Higgs VEVs to be in the ratio

It is led to conclude that the calculation of the box diagrams in the 't Hooft--Feynman gauge does give the major contribution as in this gauge other finite contributions would depend on physical-Higgs-boson masses or be suppressed by further Yukawa coupling constants.
Small, even vanishing neutrino masses are consistent with large CP violation effects in the leptonic sector. As an example, and a proof of existence of this situation, we present a model based on the
A minimal model of spontaneous CP violation with the gauge group SU(2)L × SU(2)R × U(1)B−L
We propose and analyze a minimal model of spontaneous CP violation with the gauge symmetry SU(2)L × SU(2)R × U(1)B−L. We find that the “isoconjugate relation” of Mohapatra and Pati is no longer valid

Abstract In the QCD sum rule determination of ms using the two-point correlator of divergences of ΔS = 1 vector currents, the final uncertainty on ms is mainly due to the hadronic spectral function.
