چکیده

In view of the discovery potential associated with the future experiments of high-luminosity xed target facilities, B-meson factories and-charm factories, we highlight some typical signals of D 0-D 0 mixing and CP violation which are likely to show up in neutral D-meson decays to the semileptonic nal states, the hadronic CP eigenstates, the hadronic non-CP eigenstates and the CP-forbidden states. Both time-dependent and time-integrated measurements are discussed, and particular interest is paid to D 0 =

New Time Distributions of D-D̄ or B-B̄ Mixing and CP Violation

The formulae for D0-D̄0 or B0-B̄0 mixing and CP violation at the τ -charm or Bmeson factories are derived, for the case that only the decay-time distribution of one D or B meson is to be measured. In particular, we point out a new possibility to determine the D0-D̄0 mixing rate in semileptonic D decays at the Ψ(4.14) resonance; and show that both direct and indirect CP asymmetries can be measured ...

Effect of K − K̄ Mixing on CP Asymmetries in Weak Decays of D and B Mesons

Within the standard electroweak model we carry out an instructive analysis of the effect of K0 − K̄0 mixing on CP asymmetries in some weak decay modes of D and (−) B d mesons. We point out that a clean signal of CP violation with magnitude of 2Re(ǫ) ≈ 3.3 × 10−3 can manifest in the semileptonic decays D+ → lνlKS (KL) vs D − → l−ν̄lKS (KL). The CP asymmetries are also dominated by 2Re(ǫ) in the tw...

Time dependence of coherent P0P-bar0 decays and CP violation at asymmetric B factories.

A generic formalism is presented for the time-dependent or time-integrated decays of any coherent P 0 ¯ P 0 system (P 0 = K 0 , D 0 , B 0 d , or B 0 s). To meet various possible measurements at asymmetric B factories, we reanalyze some typical signals of CP violation in the coherent B 0 d ¯ B 0 d transitions. The advantage of proper time cuts is illustrated for measuring mixing parameters and C...

Various developing topics in CP violation are reviewed. There are many theoretical reasons to hope that the CKM paradigm may be incomplete. It is surely too soon to be claiming new physics in ǫ′/ǫ or in D − D̄ mixing, but rare K decays offer interesting places to search for new physics. It is probably also premature to see a clash between global CKM fits and current estimates of sin β and γ, whe...
