TL;DR
The paper discusses how the initial LHC run at 3.5 TeV can effectively probe small x gluon dynamics through vector meson photoproduction in ultraperipheral proton collisions.
Contribution
It proposes using early LHC data to test small x gluon behavior and color dipole-gluon interactions in proton-proton ultraperipheral collisions.
Findings
Potential to test small x gluon density in initial LHC run
Feasibility of studying vector meson photoproduction in ultraperipheral collisions
Insights into color dipole-gluon interaction dynamics
Abstract
We argue that already the first year run at the LHC with 3.5 TeV proton beams will provide a quick and effective way to test the dynamics of the color dipole-gluon interactions and the small x behavior of the gluon density in proton from study of the vector meson photoproduction in ultraperipheral proton-proton collisions.
