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)+ pea...

| 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 Σc+D¯0 channel opening. |
