Abstract

The f 0(l500) is observed in its KK decay mode in an amplitude analysis of high statistics data in pp annihilation at rest into π 0K LK L. The mass and width is found to be (m, Γ) = (1515 ±20,105 ±15) MeV. A comparison of the decay rate into 2π 0 shows that this state cannot be dominantly ss̄. The F′ 2(1525) has been observed for the first time in p̄p annihilation and its production rate is consistent with the expectation from the OZI rule.
