Final State Interaction Effects in B+→J/ψ π+ Decay

Effects of final state interaction in B^+_c to D^0 K^+ decay

In this paper, the decay of Bc+ meson, which consists of two b and c heavy quarks, into the Do and K+  mesons was studied. Given that the experimental branching ratio for this decay was within the range of 3.75*10-5 to 11.16*10-5; it was decided to calculate the theoretical branching ratio by applying the final state interaction (FSI) through the T and cross-section channels. In this process, b...

Final State Interaction in Heavy Hadron Decay

Though nothing is known for B → ππ,Kπ,KK, we might conjecture that the FSI phases diminish as the initial mass increases. Meanwhile the relative FSI phase is known for the ggg and ”γ” decay amplitudes of the J/ψ decays: 3 ∆δ ≈ 90 and 75 for J/ψ → 00 and 01, respectively. Therefore, if the FSI phases diminish with the increasing initial mass, it should start diminishing somewhere between mJ/ψ an...

Long - range final - state interactions and direct CP asymmetry in B + → π + K 0 decay

Final-state Interactions in the Decay B

In this article, we study the final-state rescattering effects in the decay B0 → ηcK, the numerical results indicate the corrections are comparable with the contribution from the naive factorizable amplitude, and the total amplitudes can accommodate the experimental data. PACS numbers: 13.20.He; 14.40.Lb

Final State Interactions in Hypernuclear Decay

We present an update of the One-Meson-Exchange (OME) results for the weak decay of sand p-shell hypernuclei [1], paying special attention to the role played by final state interactions between the emitted nucleons. The present study also corrects for a mistake in the inclusion of the K and K exchange mechanisms, which substantially increases the ratio of neutroninduced to proton-induced transit...

Final-state Phases in B → Dπ, D ∗ Π, And

The final-state phases in B → Dπ, Dπ, and Dρ decays appear to follow a pattern similar to those in D → Kπ, K∗π, and Kρ decays. Each set of processes is characterized by three charge states but only two independent amplitudes, so the amplitudes form triangles in the complex plane. For the first two sets the triangles appear to have non-zero area, while for the Dρ or Kρ decays the areas of the tr...
