GPD Evolution for a Scalar Particle

We study the Generalized Parton Distribution (GPD) parameterization which aims at investigating how accurately GPDs can be extracted from DVCS data taken over a wide range of Q$^{2}$. The results indicate that from mathematical point of view a unique GPD extraction is possible. We have investigated that how experimental uncertainties and the limited range over which DVCS data will impede the GPD extraction.
