Abstract

We report the observation of a narrow charmoniumlike state produced in the exclusive decay process [Formula presented]. This state, which decays into [Formula presented], has a mass of [Formula presented], a value that is very near the [Formula presented] mass threshold. The results are based on an analysis of 152M [Formula presented]-[Formula presented] events collected at the [Formula presented] resonance in the Belle detector at the KEKB collider. The signal has a statistical significance that is in excess of [Formula presented].
