Title: Interpretation of the LHCb P c ( 4312 ) + Signal

Abstract

We study the nature of the new signal reported by LHCb in the $J/Ψp$ spectrum. Based on the S-matrix principles, we perform a minimum-bias analysis of the underlying reaction amplitude, focusing on the analytic properties that can be related to the microscopic origin of the $$P_c$$(4312) + peak. By exploring several amplitude parameterizations, we find evidence for the attractive effect of the $$Σ^+_c$$$\bar{D}^0$$ channel, that is not strong enough, however, to form a bound state.
