Abstract

Using data collected near the Ds*+Ds- peak production energy Ecm=4170MeV by the CLEO-c detector, we study the decays of Ds+ mesons to two pseudoscalar mesons. We report on searches for the singly Cabibbo-suppressed Ds+ decay modes K+η, K+η′, π+KS0, K+π0, and the isospin-forbidden decay mode Ds+→π+π0. We normalize with respect to the Cabibbo-favored Ds+ modes π+η, π+η′, and K+KS0, and obtain ratios of branching fractions: B(Ds+→K+η)/B(Ds+→π+η) =(8.9±1.5±0.4)%, B(Ds+→K+η′)/ B(Ds+→π+η′)=(4.2±1.3±0.3)%, B(Ds+→π+KS0) /B(Ds+→K+KS0)=(8.2±0.9±0.2)%, B(Ds+→K+π0)/ B(Ds+→K+KS0)=(5.5±1.3±0.7)%, and B(Ds+→π+π0)/ B(Ds+→K+KS0)<4.1% at 90% C.L., where the uncertainties are statistical and systematic, respectively.

N2 - Using data collected near the Ds*+Ds- peak production energy Ecm=4170MeV by the CLEO-c detector, we study the decays of Ds+ mesons to two pseudoscalar mesons. We report on searches for the singly Cabibbo-suppressed Ds+ decay modes K+η, K+η′, π+KS0, K+π0, and the isospin-forbidden decay mode Ds+→π+π0. We normalize with respect to the Cabibbo-favored Ds+ modes π+η, π+η′, and K+KS0, and obtain ratios of branching fractions: B(Ds+→K+η)/B(Ds+→π+η) =(8.9±1.5±0.4)%, B(Ds+→K+η′)/ B(Ds+→π+η′)=(4.2±1.3±0.3)%, B(Ds+→π+KS0) /B(Ds+→K+KS0)=(8.2±0.9±0.2)%, B(Ds+→K+π0)/ B(Ds+→K+KS0)=(5.5±1.3±0.7)%, and B(Ds+→π+π0)/ B(Ds+→K+KS0)<4.1% at 90% C.L., where the uncertainties are statistical and systematic, respectively.
