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.

Understanding the newly observed heavy pentaquark candidates
TL;DR: In this article, the anomalous triangle singularity (ATS) transitions in the specific kinematics of Λ b → J / ψ K − p were investigated and several thresholds can contribute to the enhancements of the newly observed heavy pentaquark candidates.

Peaks within peaks and the possible two-peak structure of the P c ( 4457 ) : The effective field theory perspective
TL;DR: In this article, the LHCb pentaquarks (P_c(4312), $P-c(4440) and $Pc(4457)$) contain in addition a ε-Lambda(2595) \bar{D} component in P-wave, which happens to be unusually long-range.

On the hidden charm pentaquark-s in $\Lambda_b \to J/\psi K^- p$ decay
TL;DR: In this paper, the authors improved upon the previous work by considering all the relevant resonances contributing to the spectra, and discussed the possible nature of both $P_c(4380)^+$ and $P-c(4450)+$ signals, and also discussed several important topics, like the effect of the contact term in the reaction, the viability of reproducing the data without the $P c(43 80)^+)$ and the possible quantum numbers assignment to these pentaquarks.
