The high prompt production cross section of X 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 ppbar 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 Z(4020).

Abstract
The high prompt production cross section of X 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 ppbar 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 Z(4020).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
