- Abstract
- Using a data sample of 980 fb(-1) collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider, we study for the first time the singly Cabibbo-suppressed decays omega(0)(c) -(sic) -pi(+) and omega K--(+) and the doubly Cabibbo-suppressed decay omega(0)(c) -(sic)K--(+). Evidence for an Q0 c signal in the omega(0)(c) -E-pi+ mode is reported with a significance of 4.5 sigma including systematic uncertainties. The ratio of branching fractions to the normalization mode omega(0)(c) -omega(-)pi(+ )is measured to beB(omega(0)(c) -(sic)(-)pi(+))/B(omega(0)(c) -Q-pi+) = 0.253 +/- 0.052(stat.) +/- 0.030(syst.).No significant signals of omega(0)(c) -(sic)K--(+) and omega K--(+) modes are found. The upper limits at 90% confidence level on ratios of branching fractions are determined to beB(omega(0)(c) -> (sic)K--(+))/B(omega(0)(c) -> omega-pi(+)) < 0.070 andB(omega(0)(c) -> omega K--(+))/B(omega(0)(c) -> omega-pi(+)) < 0.29.
