We analyze the X (3872) production in the processes (D) over barD -> pi X, (D) over bar *D -> pi X, and (D) over bar *D -> pi X, making use of heavy meson effective theory, with an effective Lagrangian built based on chiral SU(3)(L)xSU(3)(R) and heavy quark symmetries. In this scenario, we consider the X (3872) as a bound state of D*(D) over bar+ c.c., including neutral and charged components, and obtain the cross sections of the mentioned reactions as functions of the collision energy.
