Abstract
Using the one-boson-exchange model,we studied the possible existence of very loosely bound hidden-charm molecular baryons composed of an anti-charmed meson and a charmed baryon.Our numerical results indicate that the Σ c * and Σ c  states exist,but that the Λ c  and Λ c * molecular states do not.

Is the pentaquark doublet a hadronic molecule

TL;DR: In this article, a doublet of overlapping pentaquark resonances has been discovered and the origin of this doublet structure was investigated, and it was shown that such degeneracy could naturally arise if constituent hadrons were in the colored, rather than colorless states.

Interpreting the X (5568)

TL;DR: In this paper, a variety of options for interpreting the DO state, X ( 5568 ), are examined and it is shown that threshold, cusp, molecular, and tetraquark models are all unfavoured.

Possible strange hidden-charm pentaquarks from and interactions*

TL;DR: Using the one-boson-exchange model, this paper investigated the Lambda(c)(D) over bar (s)*, Sigma(c),D over bar, Xi(c)'s over bar*, and Xi's* over bar* interactions by considering one-eta exchange and/or one-pion exchange contributions and predicted the existence of hidden-charm molecular pentaquarks.

Towards exotic hidden-charm pentaquarks in QCD

TL;DR: A QCD sum rule investigation is performed, by which they can be identified as exotic hidden-charm pentaquarks composed of an anticharmed meson and a charmed baryon, and results suggest that P(c)(4380) and P (c)(4450) have quantum numbers J(P)=3/2(-) and 5/2 (+), respectively.

The Pentaquark Candidates in the Dynamical Diquark Picture

TL;DR: In this paper, the authors describe the pentaquark candidates P c + ( 4380 ) and P c+ ( 4450 ) in terms of a confined but rapidly separating color-antitriplet diquark cu and color-triplet triquark cu.
