8 Jul 2009 | Abstract: | In this work, we study the radiative open-charm decays $Y(4140) o
{D}_s^{ast+} D_s^- gamma$ and $Y(3930) o{D}^{ast+} D^-gamma$ under the
assignments of $D_{s}^*ar{D}_s^*$ and $D^*ar{D}^*$ molecular states for
Y(4140) and Y(3930) respectively. Basing on our numerical result, we propose
that the experimental measurement of the photon spectrum of $Y(4140) o
{D}_s^{ast+} D_s^- gamma, D_{s}^+D_{s}^{*-}gamma$ and $Y(3930) o
D^{*0}ar{D}^0gamma, D^{0}ar{D}^{*0}gamma, D^{*+}D^-gamma,
D^+D^{*-}gamma$ can further test the molecular assignment for Y(4140) and
Y(3930). | Source: | arXiv, 0907.1349 | Services: | Forum | Review | PDF | Favorites |
