A partial wave analysis of the centrally produced $K^{+}K^{-}$ and $K^{0}_{s}K^{0}_{s}$ systems in pp interactions at 450 GeV/c and new information on the spin of the $f_{1}$ (1710)

Abstract : A partial wave analysis of the centrally produced K+K- and K0K0 channels 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 corresponding to the f0(1500) and fJ(1710) with J = 0. The D-wave shows evidence for the f2(1270)/a2(1320), the f2(1525) and the f2(2150) but there is no evidence for a statistically significant contribution in the D-wave in the 1.7 GeV mass region.
