Abstract

We study factorizable contributions to two-body nonleptonic decays of B mesons using the light-cone sum rule method. By constructing three-point correlation functions and incorporating light-cone distribution amplitudes, we compute the hadronic matrix elements and branching ratios for decay channels B⁰ → π⁺π^-, B⁺ → π⁺π⁰, B⁰ → K⁺π^-, and B⁰ → K⁺K^-. The results are in agreement with experimental data within uncertainties. We also estimate the branching ratio of B_s⁰ → π⁺π^- to be approximately 0.781×10^-6.
