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...
