The hidden-charm pentaquark and tetraquark states

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.
Journal ArticleDOI

Hadronic molecules

TL;DR: In this article, the authors review experimental evidences of various candidates of hadronic molecules, and methods of identifying such structures Nonrelativistic effective field theories are the suitable framework for studying hadronic molecule, and are discussed in both the continuum and finite volumes.

Nonstandard heavy mesons and baryons: Experimental evidence

TL;DR: Recently, a variety of QCD inspired phenomenological models have been proposed, such as meson-gluon hybrids and pentaquark baryons that contain heavy (charm or bottom) quarks as mentioned in this paper.
Journal ArticleDOI

Pentaquark and Tetraquark 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.
