英文摘要	We report the observation of b-s(0) -> j/psi f(0(980)) and evidence for b-s(0) -> j/psi f(0)(1370), which are cp eignstate decay modes. these results are obtained from 121.4 fb(-1) of data collected at the y(5s) resonance with the belle detector at the kekb e(+)e(-) collider. we measure the branching fractions b(b-s(0) -> j/psi f(0)(980); f(0)(980) -> pi(+)pi(-)) = (1.16(-0.19)(+0.31)(stat)(-0.17)(+0.15)(syst)(-0.18)(+0.26)(n-bs(*)(b) over bars(*))) x 10(-4) with a significance of 8.4 sigma, and b(b-s(0) -> j/psi f(0)(1370); f(0)(1370) -> pi(+)pi(-)) = (0.34(-0.14)(+0.11)(stat)(-0.02)(+0.03)(syst)(-0.05)(+0.08) (n-bs(*)(b) over bars(*))) x 10(-4) with a significance of 4.2 sigma. the last error listed is due to uncertainty in the number of produced b-s((*)) (b) over bar ((*))(s) pairs.
