### Abstract

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