Absolute measurement of hadronic branching fractions of the D-s(+) meson

The branching fractions of D-s(+/-) meson decays serve to normalize many measurements of processes involving charm quarks. Using 298 pb(-1) of e(+)e(-) collisions recorded at a center of mass energy of 4.17 GeV, we determine absolute branching fractions for eight D-s(+/-) decays with a double tag technique. In particular we determine the branching fraction B(D-s(+)-> K-K+pi(+))=(5.50 +/- 0.23 +/- 0.16)%, where the uncertainties are statistical and systematic, respectively. We also provide partial branching fractions for kinematic subsets of the K-K+pi(+) decay mode.
