New Spectroscopy of Heavy Mesons    [PDF]

Fulvia De Fazio

I discuss the most recently discovered open charm mesons, both with and without strangeness. By exploiting the heavy quark limit, strong decay widths of such mesons are computed. Comparison between theoretical predictions and experimental measurements are useful to assign the right quantum numbers to such states. As for hidden charm mesons, I consider the case of X(3872). Analysis of its radiative decays to $J/\psi \gamma$ and $\psi(2S) \gamma$ shows the plausibility of the identification with $\chi_{c1}(2P)$.
