Deeply Virtual Compton Scattering in improved holographic QCD

We present our current progress in the holographic computation of the scattering amplitude for Deeply Virtual Compton Scattering (DVCS) processes, as a function of the Mandelstam invariant t. We show that it is possible to describe simultaneously the differential cross-section and total cross-section of DVCS data with a single holographic model for the pomeron. Using data from H1-ZEUS we obtained a chi(2)(dof) similar to 1.5 for the best fit to the data. (C) 2021 The Author(s). Published by Elsevier B.V.

Automated summary

The study presents the holographic computation of the scattering amplitude for Deeply Virtual Compton Scattering (DVCS) processes, and shows the possibility of describing DVCS data with a single holographic model for the pomeron. The best fit to the data obtained a chi(2)(dof) of around 1.5 using data from H1-ZEUS.
