Abstract
The f 0(1500) is observed in its K K decay mode in an amplitude analysis of high statistics data in pp annihilation at rest into π 0 K L K L . The mass and width is found to be ( m, Γ) = (1515 ± 20, 105 ± 15) MeV. A comparison of the decay rate into 2 π 0 shows that this state cannot be dominantly s s . The f′ 2(1525) has been observed for the first time in pp annihilation and its production rate is consistent with the expectation from the OZI rule.
