“…In the standard model (SM), the only sources of CP-violating (CPV) are the Cabbibo-Kobayashi-Maskawa (CKM) phases, which appears to be the origin of the CPV phenomena observed in nondiagonal processes involving the K and B mesons [1][2][3]. However, the observed baryon asymmetry of the universe indicates that, the CPV sources in the SM are not sufficient, and new CPV sources are needed to generate the observed baryon asymmetry.…”

The searching for the electric dipole moments (EDMs) of neutron (d n ), b quark (d b ) and c quark (d c ) gives strict upper bounds on these quantities. And recently, new upper bounds on d b , d c are obtained by the strict limit on d n . The models of new physics (NP) with additional CP-violating (CPV) sources are constrained strictly by these EDMs. In this work, we focus on the CPV effects on these EDMs in the minimal supersymmetric extension (MSSM) of the SM with local B −L gauge symmetry (B-LSSM). The contributions from one-loop and some two-loop diagrams to the quark EDM are given in general form, which can also be used in the calculation of quark EDM in other models of NP. Considering the constrains from updated experimental data, the numerical results show that the two-loop corrections can make important contributions to these EDMs. Compared with the MSSM, the effects of new CPV phases and new parameters in the B-LSSM on these EDMs are also explored.

The large SU(3) F violations in the amplitudes for the D decays into a pair of pseudoscalar mesons are mainly accounted by the final state interaction and by contributions related to the non conservation of the strangeness changing vector currents of the octet. An approximate selection rule for the contributions proportional to V cb V * ub allows to predict the CP violating asymmetries in terms of only one parameter depending on the penguin contribution. The enhancement of the octet final states with respect to the 27, larger than expected, may be related to the presence of the nonet of scalar mesons with masses around the one of the D's. A similar mechanism may be responsible for the dominance of the ∆I = 1 2 term in K decays related to the large f 0 resonance with a mass near to one of the decaying particles.

“…Measurements of time-dependent CP asymmetries in B 0 meson decays through a dominant Cabibbo-Kobayashi-Maskawa (CKM) favored b → ccs amplitude [1] have provided a crucial test of the mechanism of CP violation in the Standard Model (SM) [2]. For such decays the interference between this amplitude and B 0 B 0 mixing is dominated by the single phase β = arg (−V cd V * cb /V td V * tb ) of the CKM mixing matrix.…”
