dc.description.abstractWe measure the branching fractions for seven D-s(+) two-body decays to pseudoscalar mesons, by analyzing data collected at root s = 4:178 similar to 4:226 GeV with the BESIII detector at the BEPCII collider. The branching fractions are determined to be B(D-s(+) -> K+eta ') = (2:68 +/- 0:17 +/- 0:17 +/- 0:08) x 10(-3), B(D-s(+) -> eta 'pi(+)) = (37:8 +/- 0:4 +/- 2:1 +/- 1:2) x 10(-3), B(D-s(+) -> K+eta) = (1:62 +/- 0:10 +/- 0:03 +/- 0:05) x 10(-3), B(D-s(+) -> eta pi(+)) = (17:41 +/- 0:18 +/- 0:27 +/- 0:54) x 10(-3), B(D-s(+) -> (K+Ks0)) = (15:02 +/- 0:10 +/- 0:27 +/- 0:47) x 10(-3), B(D-s(+) -> K-s(0)pi(+)) = (1:109 +/- 0:034 +/- 0:023 +/- 0:035) x 10(-3), B(D-s(+) -> K+pi(0)) = (0:748 +/- 0:049 +/- 0:018 +/- 0:023) x 10(-3), where the first uncertainties are statistical, the second are systematic, and the third are from external input branching fraction of the normalization mode D-s(+) -> K+K-pi(+). Precision of our measurements is significantly improved compared with that of the current world average values.en_US
