Double Pomeron Jet Cross Sections
We treat hadron-hadron collisions where the final state is kinematically of the kind associated with double-pomeron-exchange (DPE) and has large transverse momentum jets. We show that in addition to the conventional factorized (FDPE) contribution, there is a non-factorized (NDPE) contribution which has no pomeron beam jet. Within a simple model we compute DPE-two-jet total and differential cros...
متن کاملJet Production Cross Section with Double Pomeron Exchange
I will discuss hadron-hadron collisions where the final state is kinematically of the kind associated with double-pomeron-exchange (DPE) and has large transverse momentum jets. I will show that in addition to the conventional factorized (FDPE) contribution, there is a non-factorized (NDPE) contribution which has no pomeron beam jet. Results of calculations from a simple model of DPE for two-jet...
متن کاملTwo-gluon exchange model predictions for double Pomeron jet production.
I extend the two gluon exchange picture of elastic scattering, known as the Low-Nussinov or subtractive quark model, to predict cross sections for double pomeron exchange processes. In particular, I calculate pp̄ → pp̄qq̄ where the qq̄ partons will appear as jets separated from the final p and p̄ by large gaps in rapidity. The predicted cross section is large enough that this process should be obser...
متن کاملJet Cross Sections and Jet Shapes in Photoproduction
The main source of jets at HERA a comes from collisions between protons and quasi-real photons (Q ≈ 0, where Q is the virtuality of the photon) emitted by the electron beam (photoproduction). At lowest order QCD, two hard scattering processes contribute to jet production : the resolved process, in which a parton from the photon interacts with a parton from the proton, producing two jets in the ...
متن کاملStatus of jet cross sections to NNLO
In the near future the LHC experiments will provide us with a large sample of multi-particle final states. In order to extract information from this data, precise theoretical calculations are necessary. This implies to extend perturbative calculations for selected processes from next-toleading order (NLO) to next-to-next-to-leading order (NNLO) in the perturbative expansion in the strong coupli...
