    Both the mass (just below the D*0D̄0 threshold) and the likely quantum numbers (JPC=1++) of the X(3872) suggest that it is either a weakly bound hadronic "molecule" (X(3872)∼1/2[D*0D̄0+D̄*0D0]) or a virtual state of charmed mesons. Assuming the X(3872) is a weakly bound molecule, the scattering of neutral D and D* mesons off the X(3872) can be predicted from the X(3872) binding energy. We calculate the phase shifts and cross section for scattering of D0 and D*0 mesons and their antiparticles off the X(3872) in an effective field theory for short-range interactions. This provides another example of a three-body process, along with those in nuclear and atomic systems, that displays universal properties. It may be possible to extract the scattering within the final state interactions of Bc decays and/or other LHC events. © 2009 The American Physical Society.
