The hadronic decays of ϒ (9.46 GeV) were first studied by the PLUTO experiment at the DORIS e+e− storage ring (DESY). With the aim of determining the contribution of PLUTO to the discovery of the gluon, as members of this former collaboration we have reconsidered all the scientific material produced by PLUTO in 1978 and the first half of 1979. It results clearly that the experiment demonstrated the main decay of the ϒ (9.46 GeV) resonance to be mediated by 3 gluons, by providing evidence for…

Measurements of single-particles inclusive spectra and two-particle correlations in decays of the UPSILON(1S) resonance and in nonresonant annihilations of electrons and positrons at center-of-mass energy 10.49 GeV suggest baryon and antibaryon are more likely to be correlated at long range in upsilon decay than in continuum events.
