Abstract:	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.
