Abstract
A partial wave analysis of the centrally produced pi(+)pi(-) channel has be en performed in pp collisions using an incident beam momentum of 450 GeV/c. An unambiguous physical solution has been found. Evidence is found for the f(0)(980), f(0)(1300), f(0)(1500) and f(J)(1710) with J = 0 in the S-wave. The rho(770) is observed dominantly in the P-0(-)-wave and the f(2)(1270) is observed dominantly in the D-0(-)-wave. In addition, there is evidence f or a broad enhancement in the D-wave below 1 GeV.
