Deeply Virtual Compton Scattering in improved holographic QCD

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-sectio...
