An analysis of the centrally produced pi(+)pi(-) and pi(+)pi(-)pi(+)pi(-) mass spectra from the WA76 and WA91 experiments is presented, which shows that in the pi(+)pi(-)pi(+)pi(-) channel there are two new states, the f(0)(1450) and f(2)(1900). There is another new state in the pi(+)pi(-) channel with M = 1497 +/- 30 MeV and Gamma = 199 +/- 30 MeV, which is compatible with the f(0)(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 f(0)(1365) and f(0)(1520).
