“…Most existing work in this area considers coupling among Σ ðÃÞ cD ðÃÞ channels [7][8][9][10][11], or both Σ ðÃÞ cD ðÃÞ and Λ cD ðÃÞ channels [12][13][14][15][16][17][18][19][20], but the Λ c ð2595ÞD channel has hardly been discussed. There is some variation among the predictions of the different papers, but several identify states near the Σ cD , Σ Ã cD , and Σ cD Ã thresholds which are matched with P c ð4312Þ, P c ð4380Þ, and P c ð4440=4457Þ, respectively.…”

A molecular model of the P c ð4457Þ and P c ð4440Þ LHCb states is proposed. The model relies on channels coupled by long-range pion-exchange dynamics with features that depend crucially on the novel addition of the Λ c ð2595ÞD channel. A striking prediction of the model is the unusual combination of quantum numbers J P ð4457Þ ¼ 1=2 þ and J P ð4440Þ ¼ 3=2 −. Unlike in other models, a simultaneous description of both states is achieved without introducing additional short-range interactions. The model also gives a natural explanation for the relative widths of the states. We show that the usual molecular scenarios cannot explain the production rate of P c states in Λ b decays and that this can be resolved by including Λ c ð2595ÞD and related channels. Experimental tests and other states are discussed in the conclusions.

“…For the doubly heavy five-quark systems, we have a compact QQqqq configuration and two baryon-meson moleucle configurations, (QQq)(qq) and (Qqq)(Qq). As for the latter molecule configuration, there are theoretical studies in the meson exchange methods [54][55][56]. Here, we discuss the mass splittings of the compact QQqqq pentaquark states by considering the color-magnetic interactions between quarks and estimate their rough positions.…”

Surveying exotic pentaquarks with the typical QQqqq¯ configuration

et al. 2018

As a hot issue, exploring exotic pentaquarks is full of challenges and opportunities for both theorist and experimentalist. In this work, we focus on a type of pentaquark with the QQqqq (Q = b, c; q = u, d, s) configuration, where their mass spectrum is estimated systematically. Especially, our result indicates that there may exist some stable or narrow exotic pentaquark states. Obviously, our study may provides valuable information for further experimental search for the QQqqq pentaquarks. With the running of LHCb and forthcoming Belle II, we have a reason to believe that these predictions present here can be tested.

“…Besides, there are also many other calculations about possible hadronic molecular states, such as the combination of two mesons [23,24,25,26,27,28,29], or two baryons [30,31,32,33,34,35,36]. Similarly, one can also explain the hidden charm pentaquark states as a molecular state formed by one heavy meson and one heavy baryon [37,38,39,40,41,42,43,44,45].…”

Possible molecular states composed of doubly charmed baryons with coupled-channel effect

2020

We systematically investigate the possible molecular states composed of (1) two spin-3 2 doubly charmed baryons, and (2) a pair of spin-3 2 and spin-1 2 doubly charmed baryons. The one-boson-exchange (OBE) model is used to describe the potential between two baryons. The channel mixing effect is considered for the systems with the same quantum number (I(J P )) but different total spin (S) and orbital angular momenta (L). We also study the channel mixing effect among the systems composed of various doubly charmed baryons if they have the same quantum number. Many of the systems are good candidates of molecular states.
