2 00 2 CP - violation in K S , L → π + π − γ and K S , L → π + π − e + e − decays
The dependence of KS,L → ππγ decay probabilities on photon polarization is calculated. The phases of terms of amplitude that arise from the pion-pion interaction are obtained by using a simple realistic model of pion-pion interaction via virtual ρ-meson, instead of the ChPT. The results are compared with those of other authors and the origin of the discrepancies is explained. It is shown that t...
متن کاملReanalysis of CP Violation in K L → π + π − γ
We present a reanalysis of direct CP violation in the decay K L → π + π − γ. We point out an existing discrepancy between the theoretical and experimental definitions of ǫ ′ +−γ. Adopting the experimental definition of ǫ ′ +−γ , we estimate that ǫ ′ +−γ /ǫ could be as large as a few times 10 −4 both within the standard model and beyond. We discuss these estimates in detail and we also show how ...
متن کاملMeasurement of Γ ( K S → π + π − ( γ ) ) / Γ ( K S → π 0 π 0 )
We have measured the ratio R S = Γ(KS → π π(γ))/Γ(KS → π π) with the KLOE detector at the DAΦNE ee collider. This measurement is fully inclusive with respect to the ππγ final state. The sample of over 10 two-pion decays of tagged KS mesons allows a statistical error as low as ∼ 0.1% to be obtained. The accuracy is limited by systematic uncertainties, which are estimated primarily from data. We ...
متن کاملAngular Distribution and CP Asymmetries in the Decays B̄ → K − π + e − e + and B̄ → π − π + e − e +
The short-distance Hamiltonian describing b → s(d)e−e+ in the standard model is used to obtain the decay spectrum of B̄ → K−π+e−e+ and B̄ → π−π+e−e+, assuming the Kπ and ππ systems to be the decay products of K∗ and ρ respectively. Specific features calculated are (i) angular distribution of K− (or π−) in the K−π+ (or π−π+) centre-of-mass (c.m.) frame; (ii) angular ∗E-mail address: krueger@gtae3....
متن کاملThe CP - Violating Asymmetry in K L → π + π − e + e −
We update the theoretical analysis of the CP-violating asymmetry in the decay KL → ππee, relying on chiral perturbation theory and on the most recent phenomenological information. With the experimentally determined magnetic amplitude and branching ratio as input, the asymmetry can be calculated with good accuracy. The theoretical interpretation of the sign of the asymmetry is discussed. * Work ...
