Abstract: The structure of the proton and its role in Deeply Virtual Compton
Scattering (DVCS) are investigated using the spectator model and Generalized Parton
Distributions (GPDs). DVCS is a well established means for probing the internal structure
of the proton, and GPDs are mathematical objects that are useful for describing the
proton's structure with more complexity than Parton Distribut... read moreion Functions (PDFs). The soft
parts of the DVCS amplitudes are evaluated with a partonic interpretation by using the
framework of the spectator model, and parametrized models are formed for quark, antiquark,
and gluon GPDs. Several parameters for the GPDs are obtained by fitting the GPDs to
established PDF parametrizations, as part of an iterative fit procedure. The applications
of the GPDs and their contributions to DVCS observables are then explored.
