On the possible virtual state nature of the LHCb Pc$(4312)^+$ signal
In this contribution we study the nature of the new Pc (4312)+ signal reported by LHCb collaboration in the J/ψ p spectrum. We use S-matrix principles to perform a minimum-bias analysis of the data, focusing on the analytic properties that can be related to the microscopic origin of the Pc (4312)+ p...

| description | In this contribution we study the nature of the new Pc (4312)+ signal reported by LHCb collaboration in the J/ψ p spectrum. We use S-matrix principles to perform a minimum-bias analysis of the data, focusing on the analytic properties that can be related to the microscopic origin of the Pc (4312)+ peak. Using the scattering length approximation we find evidence for interpretation of the signal as a virtual state generated by the attractive effect of the channel opening. |

We use $S$-matrix principles to perform a minimum-bias analysis of the data, focusing on the analytic properties that can be related to the microscopic origin of the Pc$(4312)^+$ peak. Using the scattering length approximation we find evidence for interpretation of the signal as a virtual state generated by the attractive effect of the $\Sigma_c^+ \bar{D}^0$ channel opening.arXiv:2004.02920oai:cds.cern.ch:27171132020-04-06 |
