Description

Using fully reconstructed $B_s$ mesons, we measure the branching fractions for the decays of $B_s\to D_s^{(\ast )+}{D}_s^{(\ast )-}$ exclusively. Assuming these decay modes saturate decays to CP-even final states, the branching fraction determines the relative width difference between the $CP$-odd and $CP$-even $B_s$ states. The results are based on a data sample collected with the Belle detector at the $\mathrm{{\rm Y}}(5S)$ resonance with an integrated luminosity of 122 fb${}^{-1}$ at the KEKB asymmetric-energy $e^{+}{e}^{-}$ collider.
