Scalar mesons and glueball in B-decays and gluon jets
Abstract
We discuss the recent observation of f0(980) in charmless B-decays and in gluon jets which hints toward a gluonic coupling of this meson similar to eta'. Further predictions on B-decays into scalar particles are presented. Charmless B decays also show a broad K Kbar (and possibly pi pi) S-wave enhancement which we relate to the 0++ glueball. These gluonic mesons represent a sizable fraction of the theoretically derived decay rate for b -> sg.
