Abstract
Using data collected near the Ds*+Ds- peak production energy E-cm=4170 MeV by the CLEO-c detector, we study the decays of D-s(+) mesons to two pseudoscalar mesons. We report on searches for the singly Cabibbo-suppressed D-s(+) decay modes K+eta, K+eta('), pi K-+(S)0, K+pi(0), and the isospin-forbidden decay mode D-s(+)->pi(+)pi(0). We normalize with respect to the Cabibbo-favored D-s(+) modes pi(+)eta, pi(+)eta('), and (K+KS0), and obtain ratios of branching fractions: B(D-s(+)-> K+eta)/B(D-s(+)->pi(+)eta)=(8.9 +/- 1.5 +/- 0.4)%, B(D-s(+)-> K+eta('))/B(D-s(+)->pi(+)eta('))=(4.2 +/- 1.3 +/- 0.3)%, B(D-s(+)->pi K-+(S)0)/B(D-s(+)->(K+KS0))=(8.2 +/- 0.9 +/- 0.2)%, B(D-s(+)-> K+pi(0))/B(D-s(+)->(K+KS0))=(5.5 +/- 1.3 +/- 0.7)%, and B(D-s(+)->pi(+)pi(0))/B(D-s(+)->(K+KS0))< 4.1% at 90% C.L., where the uncertainties are statistical and systematic, respectively.
