High Energy Physics - Phenomenology 2025-12-10 v1

Abstract

We study factorizable contributions to two-body nonleptonic decays of BB 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 B0π+πB^0 \to \pi^+\pi^-, B+π+π0B^+ \to \pi^+\pi^0, B0K+πB^0 \to K^+\pi^-, and B0K+KB^0 \to K^+K^-. The results are in agreement with experimental data within uncertainties. We also estimate the branching ratio of Bs0π+πB_s^0 \to \pi^+\pi^- to be approximately 0.781×1060.781\times10^{-6}.
