Abstract

Results are presented of the spin-parity analysis on a sample of centrally produced mesons in the reaction pp → pslow(KsKs)pfast with 800 GeV protons on liquid hydrogen. The spin-parity analysis in the mass region between threshold and 1.58 GeV/c2 shows that the KsKs system is produced mainly in S wave. The ƒo(1500) is clearly observed in this region. Above 1.58 GeV/c2 two solution are possible, one with mainly S wave and another with mainly D wave. This ambiguity prevents a unique determination of the spin of the ƒj(1710) meson.
