Measurement of the branching fractions of $D_s^{+}\to {\eta }^{\prime }X$ and $D_s^{+}\to {\eta }^{\prime }{\rho }^{+}$ in $e^{+}{e}^{-}\to D_s^{+}{D}_s^{-}$

Abstract

We study $D_s^{+}$ decays to final states involving the ${\eta }^{\prime }$ with a 482pb${}^{-1}$ data sample collected at $\sqrt{s}$ = 4.009GeV with the \mbox{BESIII} detector at the BEPCII collider. We measure the branching fractions $\mathcal{B}(D_s^{+}\to {\eta }^{\prime }X)$ = (8.8$\pm$1.8$\pm$0.5)$\%$ and $\mathcal{B}(D_s^{+}\to {\eta }^{\prime }{\rho }^{+})$ = ($5.8\pm 1.4\pm 0.4$)$\%$ where the first uncertainty is statistical and the second is systematic. In addition, we estimate an upper limit on the non-resonant branching ratio $\mathcal{B}(D_s^{+}\to {\eta }^{\prime }{\pi }^{+}{\pi }^0)<5.1\%$ at the 90$\%$ confidence level. Our results are consistent with CLEO's recent measurements and help to resolve the disagreement between the theoretical prediction and CLEO's previous measurement of $\mathcal{B}(D_s^{+}\to {\eta }^{\prime }{\rho }^{+})$.
