Resumen

Abstract The role of the triangle mechanism in the decay processes and is probed. In these processes, the triangle singularity appears from the decay of into , and then, ϕ decays into and merged into or , which finally decay into and , respectively. We find that this mechanism leads to a triangle singularity around and gives sizable branching fractions and . This investigation can help us obtain the information of the scalar meson or .
