The line shape of the radiative open-charm decay of Y(4140) and Y(3930)

Xiang Liu, Hong-Wei Ke

In this work, we study the radiative open-charm decays $Y (4140) \to D_{s}^{*+} D_{s}^{-} γ$ and $Y (3930) \to D^{*+} D^{-} γ$ under the assignments of $D_{s}^{*} D ˉ_{s}^{*}$ and $D^*\ba…

Interpretation of the " $f_{D_{s}}$ puzzle" in SM and beyond

Zheng-Tao Wei, Hong-Wei Ke, Xiao-Feng Yang

The recent measurement on the decay constant of $D_{s}$ shows a discrepancy between theory and experiment. We study the leptonic and semileptonic decays of $D$ and $D_{s}$ simultaneous…
