Exploring a ${\Sigma }_c\bar{D}$ state: with focus on $P_c(4312{)}^{+}$

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 $4.07\sim4.97~\mbox{GeV}$ 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.
