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 …
