Starting with the dynamical picture of the exotic c[¯over c]-containing states XYZas the confinement-induced hadronization of a rapidly separating pair of a compact diquark and antidiquark, we describe the pentaquark candidates P[+ over c](4380)and P[+ over c](4450)in terms of a confined but rapidly separating color-antitriplet diquark cuand color-triplet “triquark” [¯ over c](ud). This separation explains the relatively small P[+ over c] widths, despite these 5-quark systems lying far above both the J/ψp and Ac [¯ over D](∗)0 thresholds. The P[+ over c] states are predicted to form isospin doublets with neutral partners P[0 over c].
