- Abstract
In this paper, the hadronic decays B+→J/ψρ+ and B0→J/ψρ0 have been analyzed in "QCD factorization" method. The effective coefficients $a^h_i$ have been calculated for three helicity states (h = 0, +, -) which given three contributions of amplitude. We have assumed two scenarios for J/ψ. First, we have considered that J/ψ behaves as a light meson in comparison with B-meson and in other scenario, we have considered mass of J/ψ in our calculations. The branching ratios are calculated in these conditions and also in different energy scales. The obtained results are in agreement with available experimental data at second scenario and μ = mb/2.
