Production of Tetraquarks at the LHC

TL;DR

This paper investigates the production mechanisms of tetraquarks at the LHC using Monte Carlo hadronization methods, aiming to clarify their quark structure and compare their production with other exotic states like antideuterons.

Contribution

It introduces a novel approach to study tetraquark production through Monte Carlo simulations and compares their cross sections with other exotic particles to enhance understanding of their nature.

Findings

Monte Carlo hadronization models can effectively simulate tetraquark production.

Comparison with antideuteron production provides insights into tetraquark formation.

Results support diquark-antidiquark models for exotic states.

Abstract

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).
