$X(3872)$ production in high energy heavy ion collisions

We show the results obtained for the cross sections of the processes $\bar D D$,$\bar D^* D$,$\bar D^* D^\to\pi X(3872)$, information which is necessary to determine the $X(3872)$ abundance in heavy ion collisions. Our formalism is based on the generation of $X(3872)$ from the interaction of the hadrons $\bar D^0 D^{0} - $\text{c.c}$$,$D^- D^{+} - $\text{c.c}$$and$D^-_s D^{+}_s - $\text{c.c}$$anthecalculationofthe$X\bar D^* D^*$ anomalous vertex considering $X(3872)$ as a molecule of the above hadrons channels.
