Recent BaBar Results on Hadron Spectroscopy

Recent results from on hadronic spectroscopy are presented, based on data collected by the BaBar experiment between 1999 and 2004. The properties of the recently discovered D*sJ (2317)+ and DsJ (2460)+ states are studied: resonance parameters and ratios of decay rates are measured from continuum e+e- production, and production rates are measured from B decays. A search for the D*sJ (2632)+ state whose observation has been recently reported by the SELEX Collaboration, and a search for a charged partner of the charmonium-like X(3872) state, are performed, yielding negative results. Finally, extensive searches for several pentaquark candidates, both fully inclusive and in B decays, result in no positive evidence. (author)
