We revisit the application of the Froissart-Gribov (FG) projections in theanalysis of amplitudes for the Deeply Virtual Compton Scattering (DVCS),providing essential information on generalized parton distributions (GPDs). Thepivotal role of these projections in a systematic description of a hadron'sresponse to the string-like QCD probes characterised by different values ofangular momentum $J$ is emphasised. For the first time, we establish arelationship between the FG projections and GPDs for spin-$\frac{1}{2}$targets, and we investigate these quantities in various GPD models. Finally, weprovide the first numerical estimates for the FG projections based on the DVCSamplitudes directly extracted from experimental data. We argue the method ofthe FG projections deserves a broad application in the DVCS phenomenology.
