Abstract

The present day experimental data on the X(3872) decays do not allow us to make clear conclusions about the dominant structure of this state. We discuss here an alternative way to study its structure by means of the two-step D∗ (or D) production in pA reactions. If this process is mediated by X(3872), the characteristic narrow peaks of the D∗ (or D) distributions in the light cone momentum fraction at small transverse momenta will appear. This would unambiguously signal the DD∗ + c.c. molecular composition of the X(3872) state.
