Hidden-charm and bottom meson-baryon molecules coupled with five-quark states

Abstract: In this paper, we investigate the hidden-charm pentaquarks asD ( * ) Λ c andD ( * ) Σ ( * ) c molecules coupled to the five-quark states. Furthermore, we extend our calculations to the hidden-bottom sector. The coupling to the five-quark states is treated as the short range potential, where the relative strength for the meson-baryon channels is determined by the structure of the five-quark states. We found that resonant and/or bound states appear in both the charm and bottom sectors.The five-quark state potent… Show more

“…In Refs. [34,38], the short-range interaction in the P c pentaquarks are studied, which is derived based on the quark cluster model. The contributions from the color magnetic interaction of ccuud are evaluated, and they find that the ccuud configurations having the other spin j ¼ 3=2 are important to produce an attraction.…”

“…In 2015, the Large Hadron Collider beauty experiment (LHCb) Collaboration announced the observation of two hidden-charm pentaquarks, P Before the LHCb observation, some theoretical studies of hidden-charm pentaquarks were done [4][5][6][7]. After the LHCb announcement, there were many analyses based on the hadronic molecular state [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24], compact pentaquark state [25][26][27][28][29][30][31][32][33], quark-cluster model [34], baryocharmonium model [35], hadroquarkonia model [36], topologial soliton model [37], and meson-baryon molecules coupled with five-quark states [38]. The kinematical rescattering effects are also discussed in Refs.…”

“…threshold, one more state around the P c ð4440Þ þ is expected. If short-range interactions are considered, the number of molecular states will be reduced because of the forbidden states [60]. Therefore, the full J=ψp spectrum is also helpful to establish state assignments.…”
