The X(3872) and other X,Y,Z Resonances as Hidden Charm Meson-Meson Molecules

Abstract

We report on some ideas concerning the nature of the X(3872) resonance and the need for approximately equal charged and neutral components of $D{\bar{D}}^{\ast }+cc$. Then we discuss how some hidden charm states are obtained from the interaction between vector mesons with charm and can be associated to some of the charmonium-like X,Y,Z states. Finally we discuss how the nature of these states could be investigated through different types of radiative decay.
