Probing small x parton densities in ultraperipheral AA and pAcollisions at the LHC

PDF Version Also Available for Download.

Description

We calculate photoproduction rates for several hard processes in ultraperipheral proton-lead and lead-lead collisions at the LHC with {radical}s{sub NN} = 8.8 and 5.5 TeV respectively which could be triggered in the large LHC detectors. We use ATLAS as an example. The lead ion is treated as a source of (coherently produced) photons with energies and intensities greater than those of equivalent ep collisions at HERA.We find very large rates for both inclusive and diffractive production which will extend the HERA x range by nearly an order of magnitude for similar virtualities. We demonstrate that it is possible to reach ... continued below

We demonstrate that it is possible to reach the kinematic regime where nonlinear effects are larger than at HERA.
