Abstract
The precise measurement of binding energy, total width and DD pi branching fraction, constrains, in a model independent way, the loosely bound hadron molecule interpretation of X(3872). A full discernment is not yet possible on the basis of present data. Similar considerations might be extended to all those Y, Z resonances susceptible of a molecular description. (C) 2015 The Author.
