Quark-nucleon dynamics and Deep Virtual Compton Scattering
M. Gorchtein, A.P. Szczepaniak
TL;DR
This paper investigates how Regge exchanges, especially Pomeron exchange, influence deeply virtual Compton scattering and deep inelastic scattering, demonstrating Regge scaling and comparing theoretical predictions with HERA experimental data.
Contribution
It introduces a model incorporating Regge exchanges into the quark-nucleon amplitude to explain scattering behaviors and compares these with experimental results.
Findings
Regge exchanges induce Regge scaling in the Compton amplitude.
Pomeron exchange significantly contributes to the scattering process.
Model predictions align with HERA data.
Abstract
We consider deeply virtual Compton scattering and deep inelastic scattering in presence of Regge exchanges that are part of the non-perturbative quark-nucleon amplitude. In particular we discuss contribution from the Pomeron exchange and demonstrate how it leads to Regge scaling of the Compton amplitude. Comparison with HERA data is given.
