TL;DR: Recently, the LHCb Collaboration discovered two hidden-charm pentaquark states, which are also beyond the quark model as discussed by the authors, and investigated various theoretical interpretations of these candidates of the multiquark states.

TL;DR: Recently, the LHCb collaboration not only confirmed the existence of the hidden-charm pentaquarks, but also provided strong evidence of the molecular picture as discussed by the authors, where the authors reviewed the experimental and theoretical efforts on the hidden heavy flavor multiquark systems in the past three years.

TL;DR: In this paper, the experimental and theoretical efforts on the hidden heavy flavor multiquark systems in the past three years were reviewed extensively in [Phys. Rept. 639 (2016) 1-121].

TL;DR: A review of the experimental and theoretical progress in the field of charmed meson discovery can be found in this article, where two narrow charm-strange states $D{s0}^*(2317)$ and $D_{s1}(2460)$ were discovered by the BaBar and CLEO Collaborations, respectively.

TL;DR: The LHCb Collaboration at the Large Hadron Collider at CERN discovered two pentaquark states P_{c}(4380) and P(4450), which are interpreted as the loosely bound Σ_{c](2455)D^{*} and Σ(2520)D{*} molecular states in the boson exchange interaction model.
