Resumen

Using a dataset of (Formula presented) events collected by the BESIII detector operating at the BEPCII collider, we report the first observation of the decay (Formula presented) with a statistical significance of (Formula presented). The measured branching fraction is (Formula presented), where the first uncertainty is statistical and the second is systematic. Additionally, we investigate potential intermediate states in the invariant mass distributions of (Formula presented), (Formula presented) and (Formula presented). A hint of a resonance is observed in the invariant mass distribution of (Formula presented), located around (Formula presented), with a significance of (Formula presented).
