Abstract	The Crystal Barrel Collaboration observes scalar meson resonances in $\bar p p$ annihilation. Based on the measurements and partial wave analyses these are candidates for the $^3$P$_0$ groundstate nonet. The supernummerary $f_0(1500)$ resonance is identified as a scalar groundstate glueball. Important information for its characterization comes from the decay pattern into pseudoscalar and scalar mesons. Data on kaonic decays in the mass region up to 1700 MeV are now avaible at Crystal Barrel. New analysis results are presented.
