Measurement of $e^{+}{e}^{-}\to D_s^{(\ast )+}{D}_s^{(\ast )-}$ cross sections near threshold using initial-state radiation

Abstract

We report a measurement of exclusive $e^{+}{e}^{-}\to D_s^{(\ast )+}{D}_s^{(\ast )-}$ cross sections as a function of center-of-mass energy near $D_s^{(\ast )+}{D}_s^{(\ast )-}$ threshold with initial-state radiation. The analysis is based on a data sample collected with the Belle detector with an integrated luminosity of $967{\mathrm{fb}}^{-1}$.
