Abstract: The observation of the DsJ*(2317)+ and DsJ(2460)+ mesons, discovered in 2003, raised a lot of interest for the spectroscopy of charmed hadrons. Both DsJ particles are studied in the B meson decay channels B->DsJD(*). Theoretical explanations and experimental results are summarized. The work described is based on the analysis of the data collected at the BaBar experiment on the PEP-II collider at SLAC (Stanford Linear Accelerator Center) between 1999 and 2002. The data sample corresponds at 122.1 ± 0.6 ± 1.3 millions of BBbar pairs.
