Strong Enhancement of ε/ε Through Final State Interactions
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 final rescattering of the two pions provides a strong enhancement of the ∆I = 1/2 amplitude, which so far has been neglected in the theoretical predictions of ε′/ε. This correction increases the Standard Model prediction of ε′/ε to v...
متن کاملStrong Final State Interactions in γγ → WW
We study the effects of a possible strong final state interaction among longitudinal W 's in γγ → W W. The relevant partial wave amplitudes are modified by an Omnès function approximated by a Breit-Wigner form factor. We study the fractional cross section f 00 = σ LL /σ Total with both W 's longitudinally polarised, in the presence of a J = 2 resonance (M = 2.5 TeV, Γ = 500 GeV) or a J = 0 reso...
متن کاملThe strong coupling constant gD∗Dπ and final-state interactions
In this article, we study the contribution from the final-state interactions to the strong coupling constant gD∗Dπ. We take an assumption that the momentum transfers in the strong decay D∗+ → Dπ be large to validate the operator product expansion in the light-cone QCD sum rules. At large momentum transfers, the final-state interactions play an important role, and we should take them into accoun...
متن کاملFinal State Interactions
Precise measurements of the mass and width of the W boson are carried out in e + e − collisions at Lep, by kinematic reconstruction of the invariant mass distributions of W + W − → qq ′ ℓν ℓ and W + W − → qq ′ qq ′ candidate events. The most recent combination of such results from Aleph, Delphi, L3 and Opal uses approximately 82% of the final Lep2 integrated luminosity and is preliminary. The m...
متن کاملFinal State Interactions and Ε
I discuss the rôle of strong final state interactions (FSI) in K → 2π decays. In this case strong FSI effects can be resummed [1,2] by solving the Omnès problem for K → 2π amplitudes. Implications for the CP conserving ∆I = 1/2 ratio and the direct CP violation parameter ε ′ /ε are also discussed.
