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… 

Jet production measurements at the ATLAS experiment

Jet production is the dominant process at high transverse momentum in proton-proton collisions at the Large Hadron Collider and allows for a precise test of the strong interaction and the structure

JETS and QCD: a historical review of the discovery of the quark and gluon jets and its impact on QCD

AbstractThe observation of quark and gluon jets has played a crucial role in establishing Quantum Chromodynamics [QCD] as the theory of the strong interactions within the Standard Model of particle

Search for new physics in events with same sign leptons and missing energy with ATLAS at LHC

The Standard Model of particle physics describes the phenomena in the infinitesimal with great success. However, it suffers from several inadequacies : it can not explain the neutrino masses, it has

Observation of Feynman scaling violations and evidence for a new resonance at RHIC

We report measurements of forward jets and dijets produced in Cu+Au collisions at $\sqrt{s_{NN}}=200$ GeV at the Relativistic Heavy Ion Collider. We also report dijet production cross sections in p+p

We report the analysis of the spatial energy distribution of data for e+e hadrons obtained with the MARK-J detector at PETRA. We define the quantity "oblateness" to describe the flat shape of the

On the discovery of the gluon

Abstract. Quantum chromodynamics, the theory of the strong interaction, is a field theory of quarks and gluons. When it was formulated, the existence of its basic ingredients was still unproven and

Inclusive hadron production in upsilon decays and in nonresonant electron-positron annihilation at 10.49 GeV.

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.
