Quarkonium - Theory
arXiv:1107.1273
Abstract
Some recent issues in the theory of heavy quarkonium are discussed. Many of these deal with the need to extend the description of charmonium and bottomonium states beyond the simple quark-antiquark picture. Some recent progress on radiative transitions in bottomonium is also described.
