Production of tetraquarks at the LHC

This is the authors' abstract. We don't add key points for this paper.

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(p̄) 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).
