Production of J/ψ-pairs at Hera- N
نویسنده
چکیده
The production of J/ψ-pairs as a possible measure of the polarized gluon distribution ∆G(x) is studied for proton–nucleon collisions at √ s = 40 GeV (HERA-~ N). Possibilities of reconstructing the helicity state of at least one of the J/ψ’s are critically reviewed. The observation of production asymmetries in the single polarized mode of HERA-~ N is found to be not feasible.

Charm and Beauty Production at HERA–B
The HERA–B experiment at DESY has acquired a data-set of approximately 300,000 decays J/ψ→ l+l− during its 2002/2003 data-taking period. These data are used to analyze the production of heavy quarks in proton-nucleus interactions at a center-of-mass energy of 41.6 GeV. In this article, preliminary results of two measurements are discussed, a measurement of nuclear effects in the production of J...
متن کاملHigher-Order Effects on Inelastic J/ψ Photoproduction
Approximately taking into account the higher-order effects due to multiple-gluon initial-state radiation, we extract from the latest Tevatron data of prompt J/ψ hadroproduction the leading colour-octet matrix elements within the nonrelativistic-QCD (NRQCD) factorization formalism. We find that the matrix elements which describe the formation of J/ψ mesons from colour-octet cc̄ pairs in the angul...
متن کاملJ / ψ production at the Tevatron and HERA : the effect of k T smearing
We study the effects of intrinsic transverse momentum smearing on J/ψ production both at the Tevatron and at HERA. For the case of large-p T J/ψ production at the Tevatron, the effects due to k T smearing are mild. On the other hand, inelastic J/ψ photoproduction at HERA is very sensitive to the k T smearing and, in fact, with a reasonable value of k T it is possible to resolve the large-z disc...
متن کاملJ/ψ production via fragmentation at HERA
We compute the contributions to large-pT J/ψ production at HERA coming from fragmentation of gluons and charm quarks. We find that the charm quark fragmentation contribution dominates over the direct production of J/ψ via photon-gluon fusion at large-pT , while the gluon fragmentation is negligibly small over the whole range of pT . An experimental study of pT distributions of J/ψ at HERA will ...
متن کاملDouble-spin Asymmetry of J/ψ Production in Polarized Pp Collisions at Hera- N
We calculated the color-octet contribution to the double spin asymmetry of J/ψ hadroproduction with nonzero transverse momenta at fixed target energies √ s ≃ 40 GeV. It is shown that the color-octet contribution is dominant in the asymmetries. The expected asymmetries and statistical errors in a future option of HERA with longitudinally polarized protons at HERA-N should allow one to distinguis...
