Measurement of the D_(sJ)(2317) and D_(sJ)(2460) Properties in e^+ e^- --> c c-bar Production

Abstract

The properties of the $\DsTT$ and $\DsFE$ mesons are studied using 125 ${\rm fb}^{-1}$ of $e^+e^- \to c \bar{c}$ data collected by the BaBar experiment. Preliminary mass estimates of $[2318.9\pm 0.3 ({\rm stat.}) \pm 0.9 ({\rm syst.})]$ \mevcc and $[2459.4 \pm 0.3 ({\rm stat.}) \pm 1.0 ({\rm syst.})]$ \mevcc are obtained. Searches are performed for the decay to the $D_s^+$ meson along with one or more $\piz$, $\pi^+$, or $\gamma$ particles. A search is also performed for neutral and doubly-charged partners.
