Recent results from Crystal Barrel in pp → KKπ and ω4γ Original Research Article

Recent results from the Crystal Barrel experiment in View the MathML source which bear on f0(1500) and the controversial fJ(1710) are presented. If the spin of the latter is 0, both states compete for being the scalar glueball. On the other hand, fJ(1710) could be the missing View the MathML source of the 0++ nonet, or 2++. The annihilation channels ωπ0π0 and ωηπ0 have been analyzed with increased statistics. The ingredients needed to describe the Dalitz plot are discussed.
