  "abstract": "The production ratios of hidden-charm hadrons observed in nuclear collisions reflect the degree of separation that the precursor $c\\bar c$ pair develops inside the quark-gluon plasma. The respective hadronisation amplitude manifests this relation through the position-space inner products of the in-medium and in-vacuum $c\\bar c$ wave functions. The exotic $X(3872)$, whose structure accommodates a dominant loosely bound molecular component together with a smaller compact component, stands as a novel hard probe of this spatial dependence. In this Letter, relative production measurements of $J/ψ$, $ψ(2S)$ and $X(3872)$ hadrons performed by the LHC collaborations are understood through the spatial dispersion of in-medium charm anti-charm systems.",
