Exploring a ΣcD¯ state: with focus on Pc(4312)

Stimulated by the new discovery of P c ( 4312 ) + by LHCb Collaboration, we endeavor to perform the study of P c ( 4312 ) + as a Σ c D ¯ state in the framework of QCD sum rules. Taking into account the results from two sum rules, a conservative mass range 4.07 ∼ 4.97 GeV is presented for the Σ c D ¯...

Summary:Stimulated by the new discovery of P c ( 4312 ) + by LHCb Collaboration, we endeavor to perform the study of P c ( 4312 ) + as a Σ c D ¯ state in the framework of QCD sum rules. Taking into account the results from two sum rules, a conservative mass range 4.07 ∼ 4.97 GeV is presented for the Σ c D ¯ hadronic system, which agrees with the experimental data of P c ( 4312 ) + and could support its interpretation as a Σ c D ¯ state.
