Results on Charmonium(-like) and Bottomonium(-like) States from Belle and BaBar

Abstract

Spectroscopy results for Belle and BaBar are reported. A particular focus is put on new results of the X(3872) state with its radiative decays to $J$/$\psi$$\gamma$ and ${\psi }^{\prime }$$\gamma$, its decay into $J$/$\psi$3$\pi$ and the search for production in radiative Upsilon decays. Another focus is $L$=2 mesons, in particlar a possible $D$-wave assignment to the X(3872) and the confirmation of an Upsilon $D$-wave state.
