Abstract
A partial wave analysis of the centrally produced K+K and (KSKS0)-K-0 chann els has been performed in pp collisions using an incident beam momentum of 450 GeV/c. An unambiguous physical solution has been found in each channel. The striking feature is the observation of peaks in the S-wave correspondi ng to the f(0)(1500) and f(J)(1710) with J = 0. The D-wave shows evidence f or the f(2)(1270)/a(2)(1320), the f(2)'(1525) and the f(2)(2150) but there is no evidence for a statistically significant contribution in the D-wave i n the 1.7 GeV mass region.
