Diffractive and deeply virtual Compton scattering in holographic QCD
Alexander Stoffers, Ismail Zahed
TL;DR
This paper analyzes holographic dipole-dipole scattering amplitudes at strong coupling, compares theoretical differential cross sections with experimental data for proton-proton and deeply virtual Compton scattering, and explores confinement effects.
Contribution
It extends previous holographic models to include confining backgrounds and compares these results with experimental scattering data.
Findings
Holographic model reproduces qualitative features of scattering data.
Confining background influences the shape of the differential cross section.
Strong coupling effects are significant in dipole scattering amplitudes.
Abstract
We further analyze the holographic dipole-dipole scattering amplitude developed in arXiv:1202.0831, 1205.3223. Gribov diffusion at strong coupling yields the scattering amplitude in a confining background. We compare the holographic result for the differential cross section to proton-proton and deeply virtual Compton scattering data.
