The past seventeen years have witnessed tremendous progress on the experimental and
theoretical explorations of the multiquark states. The hidden-charm and hidden-bottom …

A large number of experimental discoveries especially in the heavy quarkonium sector that
did not meet the expectations of the until then very successful quark model led to a …

A celebrated and controversial hypothesis suggests that some biological systems—parts,
aspects, or groups of them—may extract important functional benefits from operating at the …

In the present work, we assign the newly observed P c (4312) as a I (JP)= 1 2 (1 2)-
molecular state composed of Σ c D¯, while P c (4440) and P c (4457) as Σ c D¯* molecular …

Inspired by the newly observed P ψ s Λ (4338) and the reported P cs (4459), we indicate the
existence of the molecular-type characteristic mass spectrum for hidden-charm pentaquark …

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 …

The LHCb Collaboration announced the observation of three narrow structures consistent
with hidden-charm pentaquark states. They are candidates of hadronic molecules formed of …

The effects of the Σ c D¯*-Λ c (2595) D¯ coupled-channel dynamics and various one-boson-
exchange (OBE) forces for the LHCb pentaquark states, P c (4440) and P c (4457), are …

We investigate the hidden-charm pentaquarks as superpositions of Λ c D¯(*) and Σ c (*)
D¯(*)(isospin I= 1/2) meson-baryon channels coupled to auudcc¯ compact core by …

A molecular model of the P c (4457) and P c (4440) LHCb states is proposed. The model
relies on channels coupled by long-range pion-exchange dynamics with features that …
