Unbiased determination of DVCS Compton Form Factors

Understand

The extraction of Compton Form Factors (CFFs) in a global analysis of almost all Deeply Virtual Compton Scattering (DVCS) proton data is presented.

• The extracted quantities are DVCS sub-amplitudes and the most basic observables which are unambiguously accessible from this process.
• The parameterizations of CFFs are constructed utilizing the artificial neural network technique allowing for an important reduction of model dependency.
• The analysis consists of such elements as feasibility studies, training of neural networks with the genetic algorithm and a careful regularization to avoid over-fitting.
