Exotic Hadrons: Review and Perspectives
TL;DR: The physics of exotic hadrons is revisited and reviewed in this paper, with emphasis on flavour configurations which have not yet been investigated and the constituent quark model of multiquark states is discussed in some detail, as it can serve as a guide for more elaborate approaches.

Pentaquark states in a diquark–triquark model
TL;DR: In this paper, the color attractive configuration of a triquark was investigated and a nonlocal light cone distribution amplitude was defined for pentaquark states, where both triquarks and diquark are not pointlike, but they have nonzero size.
