Angular distributions in $D_{s}^{*}$ decays

Abstract

The reaction $e^{+} e^{-} \to (D_{s}^{*+} D_{s}^{-} + c.c.)$ has been used with great success at the CLEO-c detector, and will be a source of valuable future data from the BES-III detector, to obtain information about the properties and decays of the $D_{s}$ and $D_{s}^{*}$ . The angular distributions of the $D_{s}^{*}$ and the final-state particles in $D_{s}^{*} \to D_{s} γ$ are needed to model the decays properly, to confirm the spin-parity assignment $J^{P} (D_{s}^{*}) = 1^{-}$ , and to model the acceptance for the rare process $D_{s}^{*} \to D_{s} e^{+} e^{-}$ . This note presents some of the necessary expressions.
