Is the X(3872) Production Cross Section at s~(1/2)=1.96 TeV Compatible with a Hadron Molecule Interpretation?

摘要

The X(3872) is universally accepted to be an exotic hadron. In this Letter, we assume that the X(3872) is a D~0D~(*0) molecule, as claimed by many authors, and attempt an estimate of its prompt production cross section at the Fermilab Tevatron. A comparison with Collider Detector at Fermilab data allows us to draw rather compelling quantitative conclusions about this statement.
