In the present work, we propose Y(4140) as the state by studying the invariant mass spectrum of the process. In the invariant mass spectrum of the process, we find a new resonance with the mass and width to be () and () MeV, respectively, which could be a good candidate of the state. The theoretical investigations on the decay behaviors of the in the present work support the assignments of the Y(4140) and Y(4080) as the and states, respectively. In addition, the state is predicted to be a very narrow state. The results in the present work could be tested by further experiments in the LHCb and forthcoming Belle II.
