On the production of hidden-flavored hadronic states at high energy

TL;DR

This paper investigates how hidden-flavored hadrons are produced at high energies, emphasizing that hidden quark pairs may not always be involved in the initial hard scattering process, with implications for understanding specific states like X(3872).

Contribution

It offers new insights into the production mechanisms of hidden-flavored hadrons, challenging previous assumptions about their participation in short-distance interactions.

Findings

Hidden quark pairs can form without participating in short-distance scattering.

Implications for the production of X(3872) in hadron collisions.

Clarification of misunderstandings in the literature about production mechanisms.

Abstract

I discuss the production mechanism of hidden-flavored hadrons at high energy. Using $e^+e^-$ collisions and light-meson pair production in high energy exclusive processes, I demonstrate that hidden quark pairs do not necessarily participate in short-distance hard scattering. Implications are then explored in a few examples. Finally, I discuss the production mechanism of $X(3872)$ in hadron collisions, where some misunderstandings have arisen in the literature.
