Abstract
An analysis of the centrally produced π+π− and π+π−π+π− mass spectra from the WA76 and WA91 experiments is presented, which shows that in the π+π−π+π− channel there are two new states, the f0(1450) and f2(1900). There is another new state in the π+π− channel with M = 1497 ± 30 MeV and Γ = 199 ± 30 MeV, which is compatible with the f0(1520) observed by the Crystal Barrel experiment. Another interpretation is discussed, where the 1450 and 1497 GeV structures are explained as being due to an interference effect between the f0(1365) and f0(1520).
