Title: Determination of the structure of the X(3872) in p¯A collisions

The structure of the X(3872) meson is unknown. Different competing models of the cc¯ exotic state X(3872) exist, including the possibilities that this state is either a mesonic molecule with dominating D0D¯*0 + c.c. composition, a cc¯qq¯ tetraquark, or a cc¯-gluon hybrid state. It is expected that the X(3872) state is rather strongly coupled to the pp¯ channel and, therefore, can be produced in pp¯ and p¯A collisions at PANDA. We propose to test the hypothetical molecular structure of X(3872) by studying the D or D¯* source stripping reactions on a nuclear residue.
