Recent results from Crystal Barrel in pp → KKπ and ω4γ

Abstract Recent results from the Crystal Barrel experiment in K K π which bear on f 0 (1500) and the controversial f J (1710) are presented. If the spin of the latter is 0, both states compete for being the scalar glueball. On the other hand, f J (1710) could be the missing s s of the 0 ++ nonet, or 2 ++ . The annihilation channels ωπ 0 π 0 and ωηπ 0 have been analyzed with increased statistics. The ingredients needed to describe the Dalitz plot are discussed.
