Ω− non-leptonic decays

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...

= 1 / 2 rule in Ω − two body non - leptonic decays

Mirror matter admixtures and isospin breaking in the |∆I| = 1/2 rule in Ω − two body non-leptonic decays Abstract We discuss a description of Ω − two body non-leptonic decays based on possible , albeit tiny, admixtures of mirror matter in ordinary hadrons. The |∆I| = 1/2 rule enhancement is obtained as a result of isospin symmetry and, more importantly, the rather large observed deviations from...

Radiative Non – Leptonic Kaon Decays

Mirror matter admixtures in Ω − two body non - leptonic decays and the | ∆ I | = 1 / 2 rule

Mirror matter admixtures in Ω − two body non-leptonic decays and the |∆I| = 1/2 rule Abstract We extend our previous analysis of mirror matter admixtures to reproduce the |∆I| = 1/2 rule predictions in the decays Ω − → Ξ − π 0 , Ω − → Ξ 0 π − , and Ω − → ΛK −. The results are satisfactory, lending credibility to the possibility that the enhancement phenomenon may be attributed to such admixtures.

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 ...
