Abstract
- We present a physically motivated parametrization of the chiral-even generalized parton distributions in the nonsinglet sector obtained from a global analysis using a set of available experimental data. Our analysis is valid in the kinematical region of intermediate Bjorken x and for Q² in the multi-GeV region which is accessible at present and currently planned facilities. Relevant data included in our fit are from the nucleon elastic form factor measurements and from deep inelastic scattering experiments. Additional information provided by lattice calculations of the higher moments of generalized parton distributions is also considered. Recently extracted observables from deeply virtual Compton scattering on the nucleon are reproduced by our fit. [ABSTRACT FROM AUTHOR]
