Radiative Non – Leptonic Kaon Decays

Semileptonic and non - leptonic B c decays

We make predictions for the exclusive semileptonic and the non-leptonic decay widths of the Bc meson. We evaluate the Bc semileptonic form factors for different decay channels in a relativistic model, and use factorization to obtain the non-leptonic decay widths. The recent discovery of the Bc meson by the CDF Collaboration [1] attracted a great deal of attention. The Bc meson is very interesti...

Non - Leptonic Two - Body B Decays

We present a general scheme and scale independent parameterization of two-body non-leptonic B decay amplitudes which includes perturbative QCD corrections as well as final state interactions in a consistent way. This parameterization is based on the Next-to-Leading effective Hamiltonian for non-leptonic B decays and on Wick contractions in the matrix elements of the local operators. Using this ...

CP Violation in Non - Leptonic Ω − Decays

We estimate the size of the CP-violating rate asymmetry for the decay Ω − → Ξπ. Within the standard model we find a value of 2 × 10 −5 , and it could be as much as ten times larger if new physics is responsible for CP violation. Even though our calculation suffers from the usual uncertainty in the estimate of hadronic matrix elements, we find a rate asymmetry that is significantly larger than t...

Ckm Matrix from Non-leptonic B-decays

We analyze the impact of the forthcoming CP-violating observables in the Bs → K + K − system, combined with the precise measurement of sin 2β , in the extraction of the CKM matrix. Computing the penguin parameters (r, θ) within QCD factorization yields a precise determination of (¯ ρ, ¯ η), reflected by a weak dependence on θ, which is shown to be a second order effect. Using the SU (3)-flavour...
