  The high prompt production cross section of X(3872) at hadron colliders has
shown to be very informative about the quark nature of the X, Y, Z states. We
present here a number of results on X production in pp(pbar) collisions
obtained with Monte Carlo hadronization methods and illustrate what can be
learned from their use to improve our understanding of exotic states. In
particular, a comparison between antideuteron and X production cross sections
is proposed. Hadronization might be the key to solve the problem of the extra
states expected in diquark-antidiquark models which are naturally favored after
the recent confirmation of the Z(4430) tetraquark, together with its lower
partners Zc(3900) and Zc'(4020).
