Inclusive jet production on the nucleus in the perturbative QCD with N c → ∞
نویسنده
چکیده
Using the recently found hA amplitude, single and double inclusive jet production rates on the nucleus are studied in the perturbative QCD with N c → ∞. Jet multiplicities are found to grow with A and energy as A 2/9 s ∆ where ∆ is the BFKL intercept. Long range correlations are found to behave as A 4/9 s 2∆ and change from negative to positive at a certain high energy.

In the framework of perturbative QCD, double inclusive cross sections for high pt parton production in nucleus-nucleus collisions are computed with multiple rescattering taken into account. The induced long-range correlations between numbers of jets at forward and backward rapidities are found to reach 10÷ 20% for light nuclei at √ s = 200 GeV/c and to be suppressed for heavy nuclei and LHC ene...

The BFKL fan diagram equation for the scattering on the nucleus is solved numerically with the eikonalized initial condition and for a realistic nuclear density. The gluon density has a soliton-like form in the log q − y space. Inclusive cross-sections for jet production in hA and AB collisions are calculated.

متن کاملInclusive jet production using the kT algorithm at CDF
This contribution presents preliminary results on the inclusive jet production in pp̄ collisions at √ s = 1.96 TeV. The measurements are carried out using the longitudinally invariant kT algorithm. The inclusive jet cross sections are measured as a function of the jet transverse momentum in five jet rapidity regions for jets in the ranges 54 < p T < 700 GeV/c and |yjet| < 2.1. The results are ba...
متن کاملInclusive cross-sections for jet production in nucleus-nucleus collisions in perturbative QCD
Inclusive cross-sections for gluon jet production are studied numerically in the perturbative QCD pomeron model for central collisions of identical nuclei at high energies. Two forms for the inclusive cross-sections, with and without emission from the triple pomeron vertex, are compared. The difference was found to reduce to a numerical factor 0.8 ÷ 0.9 for momenta below the saturation momentum...
