Final State Interactions in Kaon Decays
We quantify the important effect of strong final state interactions in the weak K → 2π amplitudes, using the measured π-π phase shifts with J = 0 and I = 0, 2. The main results of this analysis, with their implications for ε/ε and the ∆I = 1/2 rule, have been already presented in a previous paper [1]. Here we provide a detailed formal derivation of those results and further discuss the Standard...
متن کاملFinal State Interactions in Kaon Decays Revisited
We examine effects of final state interactions (FSI) in kaon decays using a new scheme without the Omnés function, and show that while ∆I = 1/2 rule is impossible to be explained in terms of FSI alone, ′/ ∼ 16.5 × 10−4 is obtained through FSI, if the calculation is concerned only with the CP-violating parts. The ππ contribution to the mL −mS mass difference is shown to be about 14%, if the size...
متن کاملFinal State Interaction Phase in B Decays
From an estimate of the meson-meson inelastic scattering at 5 GeV it is concluded that a typical strong phase in B decays to two mesons is of order of 20◦. For a particular final state an estimate of the phase depends on whether that state is more or less probable as a final state compared to those states to which it is connected by the strong interaction S matrix.

متن کاملFinal State Interaction in B → Kπ Decays
We discuss the rescattering effects in decays B → π +K. The picture we take is very simple: first, B decay into K ∗ ρ, then K∗ and ρ go to kaon and pion by exchanging a pion. We find a up to ten percent CP violation asymmetry rate. We also discuss its correction to the constraint of angle γ proposed recently.

متن کاملFinal State Interaction Effects in B+→J/ψ π+ Decay
In this research the exclusive decay of is calculated by QCD factorization (QCDF) method and final state interaction (FSI). First, the decay is calculated via QCDF method. The result that is found by using the QCDF method is less than the experimental result. So FSI is considered to solve the decay. For this decay, via the exchange of mesons are chosen for the intermedi...
