Lightest glueball and scalar meson nonet in production and decay
Abstract
Recent results concerning the evidence and classification of the JPC=0++ states, obtained with P. Minkowski, are presented: The isoscalars f0(980) and f0(1500) are classified as members of the 0++ nonet, while the broad state called f0(400-1200) and the state f0(1370) are considered as different components of a single broad resonance, the lowest-lying 0++ glueball. Furthermore, we propose the investigation of glueball production in the fragmentation region of gluon jets.
