Glueballs: A central mystery
نویسنده
چکیده
Glueball candidates and qq̄ mesons have been found to be produced with different momentum and angular dependences in the central region of pp collisions. This talk illustrates this phenomenon and explains the φ and t dependences of mesons with JPC = 0±+, 1++, 2±+. For production of 0++ and 2++ mesons the analysis reveals a systematic behaviour in the data that appears to distinguish between qq̄ and non-qq̄ or glueball candidates. An explanation is given for the absence of 0−+ glueball candidates in central production at present energies and the opportunity for their discovery at RHIC is noted. 1 e-mail: [email protected]

Scalar Glueballs and Friends
The f0(1500) is identified in three glueball favoured production mechanisms: pp̄ annihilation, ψ → γf0 and Central Production. The production rate for glueballs in ψ → γG has been quantified and the f0(1500) is found to be consistent with a glueball qq̄ mixture. We illustrate a remarkable property of central production where kinematic cuts appear to make a systematic separation between glueballs ...
متن کاملA Glueball-qq̄ filter in Central Hadron Production
We have stumbled upon a remarkable empirical feature of central meson production which separates established qq̄ mesons from glueball candidates. This does not appear to have been noted previously and we have no simple explanation for it. We suggest that glueballs and qq̄ of the same J are distinguishable due to their boson versus fermion internal structure and that this leads to a different topo...

Goethe Universität, D–60438 Frankfurt am Main, Germany The Kurchatov Institute, Russian Research Center, 123182 Moscow, Russia Abstract Within a thermal model we estimate possible multiplicities of scalar glueballs in central Au+Au collisions at AGS, SPS, RHIC and LHC energies. For the glueball mass ...
متن کاملSearch for Gluonic Mesons in Gluon Jets
The existence of glueballs, the bound states of two or more gluons, are an early expectation of QCD. Calculations on a space time lattice have confirmed this expectation in the quantitative analysis. Their existence though is still in doubt despite continued efforts over the years. The identification of the glueballs requires the analysis of production and decay properties of the candidate meso...
