Abstract

The branching fractions of Ds± meson decays serve to normalize many measurements of processes involving charm quarks. Using 586 pb^-1 of e⁺e^- collisions recorded at a center of mass energy of 4.17 GeV, we determine absolute branching fractions for 13 Ds± decays in 16 reconstructed final states with a double tag technique. In particular we make a precise measurement of the branching fraction B(D_s→K ^-K⁺π⁺)=(5.55±0.14±0.13)%, where the uncertainties are statistical and systematic, respectively. We find a significantly reduced value of B(D_s→π⁺π0η ^′) compared to the world average, and our results bring the inclusively and exclusively measured values of B(D _s→η^′X) into agreement. We also search for CP-violating asymmetries in D_s decays and measure the cross section of e⁺e^-→Ds*D_s at E_cm=4.17 GeV.
