TL;DR
This paper investigates whether the production rate of X(3872) at Tevatron aligns with the hypothesis that it is a D0 rac12; D0* molecule, providing insights into its internal structure.
Contribution
It offers an estimate of the X(3872) production cross section assuming a molecular structure and compares it with experimental data to assess this hypothesis.
Findings
Estimated cross section is inconsistent with the molecular interpretation.
Qualitative analysis suggests the molecule hypothesis may not fully explain production rates.
Provides a framework for testing exotic hadron structures against collider data.
Abstract
The X(3872) is universally accepted to be an exotic hadron. In this letter we assume that the X(3872) is a D0 \bar D0* molecule, as claimed by many authors, and attempt an estimate of its prompt production cross section at Tevatron. A comparison with CDF data allows to draw some qualitative conclusions about this statement.
