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 کاملAnomalies in ψ ( 2 S ) decay and the ρπ puzzle
We examine the so-called ρπ puzzle of the ψ(2S) decay by incorporating two inputs: One is the relative phase between the one-photon and the gluonic decay amplitude, and the other is a possible anomaly in the inclusive nonelectromagnetic decay rate of ψ(2S). We propose the possibility that in the ψ(2S) decay a hadronic decay process of long-distance origin is important in addition to the short-d...
متن کاملBaryon helicity in B decay
The unexpectedly large transverse polarization measured in the decay B → φK∗ poses the question whether it is accounted for as a strong interaction effect or possibly points to a hidden nonstandard weak interaction. We extend here the perturbative argument to the helicity structure of the two-body baryonic decay and discuss qualitatively on how the baryonic B decay modes might help us in unders...
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 کاملRelated B Decay Modes
We have searched for two-body charmless decays of B mesons to purely hadronic exclusive final states including ω or φ mesons using data collected with the CLEO II detector. With this sample of 6.6 × 106 B mesons we observe a signal for the ωK+ final state, and measure a branching fraction of B(B+ → ωK+) = (1.5 −0.6 ± 0.2) × 10−5. We also observe some evidence for the φK final state, and upper l...
