Abstract (EN): 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.
