متن کاملGluon fragmentation into heavy quarkonium.
The dominant production mechanism for heavy quark-antiquark bound states in very high energy processes is fragmentation, the splitting of a high energy parton into a quarkonium state and other partons. We show that the fragmentation functions D(z, μ) describing these processes can be calculated using perturbative QCD. We calculate the fragmentation functions for a gluon to split into S-wave qua...
متن کاملGluon fragmentation into polarized charmonium.
Gluon fragmentation to χcJ(1P ) followed by single photon emission represents the dominant source of prompt J/Ψ’s at the Tevatron for p⊥>∼6 GeV. Since fragmenting gluons are approximately transverse, their products are significantly polarized. We find that gluon fragmentation populates the helicity levels of χc1, χc2 and J/Ψ according to D χ (h=0) c1 : D χ (|h|=1) c1 ≃ 1 : 1, D χ (h=0) c2 : D χ...
متن کاملGluon Fragmentation into Glueballs and
The constituent nature of candidate gluonic mesons can be studied by comparing their production in quark and gluon jets. The production rate for such mesons depends on the colour confinement processes at the end of the perturbative evolution. Whereas we expect enhanced production of hybrids in the fragmentation region of a gluon jet, the rate for glueballs depends on the relative importance of ...
متن کاملGluon fragmentation to 1D2 quarkonia.
Gluon fragmentation to heavy J C = 2 quarkonia is studied herein. We compute these D-wave states’ polarized fragmentation functions and find that they are enhanced by large numerical prefactors. The prospects for detecting the lowest lying D2 charmonium state at the Tevatron are discussed. 10/94 1 Work supported in part by a DuBridge Fellowship and by the U.S. Dept. of Energy under DOE Grant no...
