The X(3872) and other possible XYZ molecular states
Abstract
We perform a coupled channel calculation of the DD* and c c sectors in the framework of a constituent quark model. The interaction for the DD* states is obtained using the Resonant Group Method (RGM) and the underlying quark interaction model. The coupling with the two quark system is performed using the 3 P0 model. The X(3872) is found as a molecular state with a sizable c c component. A comparison with Belle and BaBar data has been done, finding a good agreement. Other possible molecular molecular states are discussed.
