Description
Summary:In this research, the hadronic decay of is analyzed by using” QCD factorization” (QCDF) method and final state interaction (FSI). First, the decay is calculated via QCDF method and only the annihilation graphs exist in that method. Hence, the FSI must be seriously considered to solve the decay and the ππ, ρ π and ρρ via the exchange of charmed mesones are chosen for the intermediate states. To estimate the B 0  →  π + ( ρ + ) π − ( ρ − ) decays amplitudes, the QCDF method is again used. These amplitudes are used in the absorptive part of the diagrams. The experimental branching ratio of decay is less than 6 × 10 −5 and our results according to the QCDF method and FSI are 0 . 15 × 10 −5 and 5 . 68 × 10 −5 respectively.
