Abstract

We report on recent results in spectroscopy from BaBar. This includes the discovery of a new $\Lambda_c$ baryon, detailed studies of the $D^*_{sJ}(2317)^+$, $D_{sJ}(2460)^+$, X(3872) and Y(4260) particles and the first measurement of hadronic non-$B\bar{B}$ decays of the $\Upsilon(4S)$ meson.
