The X(3872) and other possible $XYZ$ molecular states

Abstract

We perform a coupled channel calculation of the $D{D}^{\ast }$ and $c\bar{c}$ sectors in the framework of a constituent quark model. The interaction for the $D{D}^{\ast }$ 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 ${}^3{P}_0$ model. The X(3872) is found as a molecular state with a sizable $c\bar{c}$ component. A comparison with Belle and BaBar data has been done, finding a good agreement. Other possible molecular molecular states are discussed.
