Abstract

We suggest looking for pure gluon hadronic states (glueballs) in Υ{hooked}→ 3g → low spherically final state (collinear gluon jets). In these events one gluon has the maximum energy, MΥ{hooked} 2, favouring fragmentation into a glueball. The signature for a true C = G + glueball is its prominence at the Υ{hooked} resonance in e+e- →Υ{hooked} → (glueball → four charged pions) + ... and its absence in qq jets off (we do not expect significant quark fragmentation into glueballs).
