Abstract
We study factorizable contributions to two-body nonleptonic decays of 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 , , , and . The results are in agreement with experimental data within uncertainties. We also estimate the branching ratio of to be approximately .
