Three hidden-charm pentaquark P c states, P c (4312), P c (4440), and P c (4457) were revealed in the Λ b 0→ J/ψ p K-process measured by LHCb using both run I and run II data …

A bstract The nature of the three narrow hidden-charm pentaquark P c states, ie, P c (4312), P c (4440) and P c (4457), is under intense discussion since their discovery from the …

Recently, the LHCb Collaboration reported a new structure P cs (4459) with a mass of 19 MeV below the Ξ c D¯* threshold. It may be a candidate of molecular state from the Ξ c D¯ …

The observation of the P_ cs (4459) P cs (4459) by the LHCb collaboration adds a new member to the set of known hidden-charm pentaquarks, which includes the P_c (4312) P c …
From a study of the line shape of the X (3872), the LHCb collaboration measures a sizeable negative effective range. This cannot be reconciled with a shallow DD¯* bound state …

The pentaquark states P c (4312), P c (4440), and P c (4457) could be nicely arranged into a multiplet of seven molecules of D¯(*) Σ c (*) dictated by heavy quark spin symmetry …
We study the magnetic moments and transition magnetic moments of P c and P cs states in the molecular picture. We first revisit the magnetic moments of P c (4312), P c (4440), and P …
