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

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