Color Octet Contribution to J/ψ Production at a Photon Linear Collider
نویسندگان
چکیده
We investigate J/ψ production at a Photon Linear Collider (PLC) in the framework of NRQCD factorization approach. It was shown that color octet contribution is dominating in charmonium production at PLC. The main fraction of J/ψ comes from the single and double resolved photon processes. Expected cross sections of charmonium states production are large enough even at pT > 5 GeV to expect several hundreds of J/ψ’s through the leptonic decays channel for a projected integral PLC luminosity of 50fb−1 Alexander von Humboldt Fellow; e-mail: [email protected].

J/ψ plus dijet associated production in two-photon collisions
We study the production of a J/ψ meson in association with one or two jets in γγ collisions concentrating on the direct-photon contribution, which is expected to be dominant for large J/ψ-meson transverse momentum and/or large dijet invariant mass. We work at leading order in the factorization formalism of nonrelativistic QCD and include all relevant colour-octet processes. We present distribut...
متن کاملAssociate J / ψ + γ Production : A Clean Probe of Unpolarized and Polarized Gluon Densities
Color-octet contributions to the associate J/ψ+γ are found to be negligible, compared to the ordinary color-singlet contribution. Within the color-singlet model the J/ψ + γ production in the leading order is possible only through gluon-gluon fusion process. Therefore, the associate J/ψ+γ production remains to be useful as a clean channel to probe the unpolarized and polarized gluon distribution...
متن کاملProduction of a forward J/ψ and a backward jet at the LHC
We study the production at the LHC of a forward J/ψ meson and a backward jet with a large rapidity separation using the BFKL formalism. We give predictions for both the Non Relativistic QCD (NRQCD) approach to charmonium production and the Color Evaporation Model. In NRQCD, we find that the S 1 part of the onium wavefunction is completely dominating the process, which makes the presented study ...
متن کاملThe J/ψ Production Associated with a Hard Photon and the Color-Octet Singnature in e+e− Annihilation
J/ψ production associated with a hard photon in ee annihilation, being of QED nature, is invastigated thoroughly in the paper. To show its influence on the observation of the color-octet singnature in the ee annihilation via J/ψ inclusive production, the cross sections of the J/ψ productions through different mechanisms at various energies are compared quantatively by presenting them in figures...
متن کاملTesting Quarkonium Production with Photoproduced J / ψ + γ
I compute the leading color-octet contributions to the process γ + p → J/ψ + γ (+X) within the non-relativistic QCD (NRQCD) factorization formalism. In the color-singlet model, J/ψ + γ can only be produced when the photon interacts through its structure function, while the color-octet mechanism allows for production of J/ψ+γ via direct photon-gluon fusion. Resolved photon processes can be easil...
