AbstractStimulated by the new discovery of $$P_{c}(4312)^{+}$$Pc(4312)+ by LHCb Collaboration, we endeavor to perform the study of $$P_{c}(4312)^{+}$$Pc(4312)+ as a $$\Sigma _{c}\bar{D}$$ΣcD¯ state in the framework of QCD sum rules. Taking into account the results from two sum rules, a conservative mass range $$4.07{\sim }4.97~\text{ GeV }$$4.07∼4.97GeV is presented for the $$\Sigma _{c}\bar{D}$$ΣcD¯ hadronic system, which agrees with the experimental data of $$P_{c}(4312)^{+}$$Pc(4312)+ and could support its interpretation as a $$\Sigma _{c}\bar{D}$$ΣcD¯ state.
