Stimulated by the new discovery of by LHCb Collaboration, we endeavor to perform the study of as a state in the framework of QCD sum rules. Taking into account the results from two sum rules, a conservative mass range is presented for the hadronic system, which agrees with the experimental data of and could support its interpretation as a state.
