Final 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...
متن کاملObama’s Counterterrorism Policy and the Washington Post’s Editorials: A Critical Discourse Analysis of Media-State Interaction
American mass media’s relation with the US government in foreign policy decision-making has been the subject of numerous studies in the interdisciplinary field of political communication. This paper reexamines the interaction between the media and the government in the US foreign policy decision-making process, analyzing the possible congruity and/or incongruity between The Washington Post...
متن کاملEffects 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...
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 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.
