Specifically, we study the line shape of the Pc(4312) signal reported by the LHCb collaboration, and we find that its most likely interpretation is that of a virtual state. This method can be applied to other near-threshold resonance candidates.6 p.application/pdfeng(c) American Physical Society, 2022QuarksPartícules (Matèria)QuarksParticlesinfo:eu-repo/semantics/article7256602023-01-26info:eu-repo/semantics/openAccess
