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.

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.
