| dc.description | To illustrate the campaign to understand heavy quarkonium systems, I focus on a puzzling new state, $X(3872) \to π^+π^- J/ψ$. Studying the influence of open-charm channels on charmonium properties leads us to propose a new charmonium spectroscopy: additional discrete charmonium levels that can be discovered as narrow resonances of charmed and anticharmed mesons. I recall some expectations for a new spectroscopy of mesons with beauty and charm, the $B_c$ ($b\bar{c}$) system. Throughout, I call attention to open issues for theory and experiment. | |
