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.

Penta-quark States with Strangeness, Hidden Charm and Beauty

Jia-Jun Wu, +1 more
TL;DR: In this paper, some new hyperon excited states were predicted to exist; meanwhile with extension from strangeness to charm and beauty, super-heavy narrow $N^*$ and $\Lambda^*) resonances with hidden charm or beauty were predicted.

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.
